DETAILED DESCRIPTION OF EMBODIMENTS

[0075] The preferred embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings to make the advantages and features of the present disclosure more easily understood by those skilled in the art, so as to make the protection scope of the present disclosure clear and definite.

[0076] Referring to an embodiment shown in FIG. 1, a global irradiation thermotherapy system based on coordinated rotation of microwave and radio frequency is provided, which mainly includes an intelligent control unit 4, a microwave rotary heating mechanism, a capacitive radio frequency rotary heating mechanism, a temperature measuring mechanism 2, a translational heat-preservation bin 1, and a rotating mechanism connected to the intelligent control unit 4.

[0077] The capacitive radio frequency rotary heating mechanism uses an annular phantom to heat up each point of the human body with a lateral radius of 0˜13 cm to form a circular high-temperature zone. The temperature gradually decreases from the center to the outside, and the temperature of the outermost fat tissue of the human body is the lowest. The microwave rotary heating mechanism utilizes microwave rotary irradiation to form an annular high temperature layer with a thickness of 2˜4 cm on the inner side of the fat, and the temperature gradually decreases from the outside to the inside. The capacitive radio frequency rotary heating mechanism and the microwave rotary heating mechanism are arranged on one or two global irradiation rings 33, and the rotating mechanism is used to drive the global irradiation ring 33 to rotate or brake according to a control program. The temperature measurement mechanism 2 uses the internal temperature data of the human body obtained by optical fiber temperature measurement technology as a reference frame, and realizes non-invasive accurate temperature measurement in vivo through the cooperation of nuclear magnetic thermal imaging technology. The translational heat-preservation bin 1 is used to carry the human body in and out of the internal space of the microwave rotary heating mechanism and the capacitive radio frequency rotary heating mechanism. The intelligent control unit 4 is used to coordinate the microwave rotary heating mechanism and the capacitive radio frequency rotary heating mechanism to rotate and irradiate heating around the human body thermotherapy area to perform deep and shallow layered complementary diathermy, and at the same time combine with the real-time accurate measurement of the temperature measurement mechanism 2 to control the temperature precisely, and achieve uniform and precise high-heat blanching throughout the entire area.

[0078] Furthermore, the temperature measurement mechanism 2 includes a nuclear magnetic thermal imaging device, an optical fiber temperature measurement device, and a data processing platform. The nuclear magnetic thermal imaging device is used for establishing a temperature field distribution map library of each temperature corresponding to the hot spot according to the scanning data of the nuclear magnetic thermal imaging device, and scanning to obtain the temperature field distribution map of the thermal treatment area of the human body; the optical fiber temperature measuring device uses non-invasive technology to obtain the temperature of several key points in the accessible part of the human body as the temperature calibration point; the data processing platform is used to combine the temperature field distribution map library scanned by the nuclear magnetic thermal imaging device to calculate the temperature field distribution map scanned by the nuclear magnetic thermal imaging device to obtain the scanning temperature data of each hot spot in the human body thermotherapy area, and according to the accurate temperature data of the temperature calibration point as a reference, error correction is performed on the scanned temperature data to obtain accurate temperature data of each hot spot in the thermotherapy area.

[0079] In an embodiment, the optical fiber temperature measurement device is a real-time, on-line, continuous point optical fiber temperature measurement system, which includes a temperature information acquisition unit, a temperature information processing unit, and a sensing fiber. The sensing fiber is a kind of anti-electromagnetic interference point temperature sensor, on which there are several optical fiber sensors.

[0080] The annular phantom 5 matched with the radio frequency rotary heating mechanism includes a liquid-injection annular capsule 51, a cylindrical rib frame 52 located inside the liquid-injection annular capsule 51, and hoops 53 located at the left and right ends of the liquid-injection annular capsule 51 in the axial direction.

[0081] The outer ring surface 511 of the liquid-injection annular capsule 51 is a cylindrical surface in contact with the radio frequency electrode plate 6. The cylindrical surface is made of a flexible insulating material and is supported by the cylindrical rib frame 52 to maintain its shape. The inner ring surface 512 is a soft and elastic structure, which is tightly attached to the outer ring surface 511 when it is not filled with solution, and is attached to the surface surrounding the body cavity 2 when the liquid 7 is filled, as a transition between the radio frequency electrode plate and the skin of the human body. The filling liquid 7 is a non-polar fluid substance, a liquid, such as carbon tetrachloride, which is injected/filled by a liquid injection nozzle 54. The filling quantity of the liquid injection nozzle is one or more, for example, the liquid-injection nozzles 54 are arranged on the upper and lower sides on the sides of the ring phantom 5 respectively.

[0082] In one embodiment, the liquid injection annular capsule 51 is composed of two C-shaped closed capsules, and the two C-shaped closed capsules are arranged up and down around the body cavity, so that the body cavity is suspended in the annular phantom 5.

[0083] In one embodiment, the cylindrical rib skeleton 52 has two C-shaped half-body structures, which facilitates the opening and closing of the liquid-injection annular capsule 51. Correspondingly, the hoop 53 has two C-shaped half-body structures, which can be opened and closed to facilitate wearing the liquid-injection annular capsule 51 on the body.

[0084] Preferably, as shown in FIG. 4, the half-body structure shown by the cylindrical rib frame is composed of a number of rigid ribs 521 arranged at intervals along the circumference of the cylindrical surface and half-rings 522 at both ends of the cylindrical ribs. The body joint can be opened and closed, allowing the body to enter the liquid-injection annular capsule 51 when opened, and maintaining a cylindrical shape when closed.

[0085] In one embodiment, the hoop 53 is located at the two ends of the liquid-injection annular capsule 51 and is combined with the two end rings of the cylindrical rib frame 52, for example, by bonding or clamping.

[0086] In one embodiment, as shown in FIG. 3, the inner ring surface 512 of the closed capsule body is a spliced structure, which can be divided into a front flexible surface layer 5121, a middle elastic surface layer 5122, and a rear flexible surface layer 5123 along its axial direction, when there is no liquid, the C-type closed capsule has no liquid type, the inner ring surface 512 shrinks close to the outer wall. When filled with liquid, the front and back flexible surface layers 5121 open, and the middle elastic surface layer 5122 elastically stretches/shrinks to the desired circumference to fit the shape of the body skin. The elastic surface layer can be selected from rubber, latex and other materials, and the front flexible surface layer 5121 and the rear flexible surface layer 5123 can be selected from rubber, waterproof cloth and other materials.

[0087] In one embodiment, the liquid-injection annular capsule 51 has an annular soft cloth 55 with a retractable inner opening at both axial ends.

[0088] In the embodiment shown in FIG. 1, the appearance of the ring phantom is a regular cylinder with the same semi-warp, which is convenient for the radio frequency plate 6 to rotate around. The annular phantom 5 simulates the body tissue here to solve the problem that the body cavity 8 is not a regular cylinder. It's a problem that the radio frequency polar plate 6 is difficult to fit tightly when rotating and irradiating, which affects the irradiating effect.

[0089] As shown in FIG. 5, when the electrode plate 6 is attached to the wall surface 56 of the outer ring surface 511, under appropriate pressure, the wall surface 56 is indented to achieve the radio frequency electrode plate 6 and the side wall tightly fitting, keeping the contact surface to the maximum. Due to the structure of the cylindrical rib frame 52, the wall surface 56 is allowed to be partially recessed, and the wall surface 56 is coated with lubricating oil to allow the radio frequency electrode plate 6 to continuously rotate and irradiate around the side wall of the annular phantom 5.

[0090] In a modified embodiment, the outer surface of the annular phantom 5 is oblong, and the radio frequency electrode plate 6 rotates around the outer surface of the oblong circle, so that the radio frequency electrode plate 6 can smoothly rotate along its outer peripheral contour. The annular phantom 5 simulates the body skin of the thin to transform the body skin with an irregular outer contour into a regular body skin, preventing the problem that the radio frequency electrode 6 cannot fit the body skin.

[0091] In a modified embodiment, the outer surface of the annular phantom 5 is an ellipse and other smooth shapes.

[0092] A microwave radio frequency coordinated rotation global radiation heat therapy method includes the following steps:

[0093] Use the intelligent control unit 4 to cooperate with the microwave rotary heating mechanism and the capacitive radio frequency rotary heating mechanism to rotate and irradiate heating around the human body thermotherapy area, and perform deep and shallow layered complementary diathermy to achieve uniform heating of all tissues in the human body thermotherapy area; the temperature measuring mechanism 2 uses the optical fiber technology to obtain the internal temperature data of the human body as the reference frame, and uses the nuclear magnetic thermal imaging technology to perform non-invasive real-time and accurate temperature measurement in the body to achieve precise temperature control and achieve uniform and accurate high heat blanching throughout the area.

[0094] The specific steps of the method will be described below in conjunction with specific embodiments and FIG. 14.

Embodiment 1

[0095] (S1) The intelligent control unit 4 uses the microwave rotary heating mechanism and the capacitive radio frequency rotary heating mechanism to rotate and irradiate the human body thermotherapy area in cooperation to perform deep and shallow layered complementary diathermy, and set and adjust the microwave and radio frequency and power according to the tolerance of the human body, guide the translational heat-preservation bin 1 with rotating radiation heating to move back and forth, so that the thermotherapy area of the human body can be heated quickly and generally evenly to 40˜41° C.

[0096] In this embodiment, the heating method of microwave combined with capacitive radio frequency rotary irradiation adopts a global irradiation ring 33 for global heating of the human body membrane. The global irradiation ring 33 is provided with one or more pairs of capacitor plates 36 and one or more microwave magnetrons 37 are arranged at intervals in the circumferential direction. One pair or more pairs of capacitor plates 36 are used for radio frequency heat transmission, and the frequency can be selected in the range of 1 MHz˜300 MHz. One or more microwave magnetrons 37 are used for microwave heating, and the frequency can be selected from 300 MHz to 3000 MHz. The capacitor plate 36 is set individually, and the power is not less than 800 W for heating, such as 1000 W. If there are multiple sets, the total power is not less than 800 W for heating. For example, two are set, one of which is 400 W and the other is 500 W. The microwave magnetron 37 is set individually, and the power is not less than 600 W for heating, such as 700 W. If there are multiple microwave magnetrons 37, the total power is not less than 600 W, for example, two are set, one of which is 400 W and the other is 300 W.

[0097] Utilizing the advantages of the deep radio frequency heating to uniformly heat the points with a radius of 0˜13 cm, and the radio frequency heating is rotary heating to avoid the overheating of the surface fat layer caused by radio frequency radiation, and it can focus the deep layer to high temperature, and use the characteristic of microwave selective heating, use rotary heating to avoid the superficial fat layer to ensure that the fat will not overheat. For the defect of insufficient heat due to radio frequency rotary radiation in the middle ring zone with a depth of 2˜6 cm, supplementary heating is performed to achieve overall uniform heating. The radio frequency should be 1 MHz˜300 MHz electromagnetic waves, and the microwave should be microwave medium and low-frequency electromagnetic waves of 300 MHz˜3000 MHz.

[0098] The following describes the global heating mechanism of the present invention with a set of human body membrane heating effect diagrams in conjunction with this embodiment.

[0099] A microwave magnetron 37 adopts 900 MHz, the first set power is 700 W (adjustable), a pair of capacitor plates 36 adopts 40 MHz, the second set power is 1000 W (adjustable), a human body phantom with a radius of 13 cm instead of a real human body section, where the outermost layer is a fat layer with a thickness of 2 cm, the middle layer of 2˜6 cm is the muscle layer, and the other tissue layer is 6˜13 cm. Place it in a 37.3° C. environment, fiber optic sensors are arranged to measure temperature from the center to the edge with different depths.

[0100] As shown in FIG. 7, the irradiated area facing the microwave magnetron 37 is the local thermotherapy area. The skin temperature outside the fat layer is used as the temperature measurement base point. When the muscle layer inside the fat layer is heated to 43° C., accurate temperature measurement by nuclear magnetic temperature measurement with optical fiber temperature measuring technology, the temperature rise is as follows: the skin temperature is 37.3° C., the fat layer is about 2 cm thick, not easy to heat, the temperature is about 38° C., the temperature of the muscle layer inside the fat layer, it decreases as the depth increases, from 43° C. to 41.5° C. . When the heating depth reaches more than 6 cm, the temperature drops sharply to below 38° C. This part of the temperature rise is related to heat conduction.

[0101] As shown in FIG. 8, the irradiation area facing the microwave magnetron 37 rotating and irradiating is an annular area. A 4 cm-thick annular high-temperature layer is formed in the inner layer of fat. Take the skin temperature outside the fat layer as the temperature measurement base point, when the muscle layer on the inner side of the fat layer is heated to 43° C., the temperature is accurately measured by nuclear magnetic temperature measurement and optical fiber temperature measurement technology. The temperature measurement result is that the fat layer is about 2 cm still difficult to heat, and the temperature is about 37.5° C. The temperature of the inner muscle layer decreases from 43° C. to 41° C. with the depth increasing, when the heating depth exceeds 6 cm, the temperature drops below 39° C.

[0102] As shown in FIG. 9, the radius of the heating circle section of the body membrane is 13 cm. The belt-shaped area where a pair of capacitor plates 36 facing each other and the body membrane passed is the effective heating area. The fat layer dissipates slowly. Take the skin temperature outside the fat layer as the temperature measurement base point, accurate temperature measurement is carried out through nuclear magnetic temperature measurement and optical fiber temperature measurement technology. The temperature measurement result is: when the temperature of the fat layer is heated to 42° C., the temperature of the muscle layer on the inner side of the fat layer decreases as the depth increases. The temperature decreased from 42° C. to 41° C. from the fat layer to the center of the section.

[0103] As shown in FIG. 10, the cross-belt-shaped area where the two pairs of capacitor plates 36 face each other to the body membrane is the effective heating area. The fat layer dissipates slowly. Take the skin temperature outside the fat layer as the temperature measurement base point, accurate temperature measurement by nuclear magnetic temperature measurement with optical fiber temperature measurement technology, the temperature measurement result is: when the temperature of the fat layer is heated to 42° C., the temperature of the muscle layer on the inner side of the fat layer decreases with the increase in depth, from 42° C. to 41.5° C., but the temperature of the cross belt in the central overlapping area rose to 43° C.

[0104] As shown in FIG. 11, when a pair of capacitive pole plates 36 rotate and heat the body membrane alone, the irradiation area facing the entire heating circle section with a radius of 13 cm, with the central temperature as the base point of temperature measurement, accurate temperature measurement by nuclear magnetic temperature measurement with optical fiber temperature measurement technology, the temperature measurement result is: when the central area is heated to 43° C., the temperature of the heating circle section increases with the increase in depth, from the central area to the fat layer, it drops from 43° C. to 39° C. The problem of overheating of the fat layer in the state is improved by rotary heating and the fat layer becomes a relatively low-heat area.

[0105] FIG. 12 shows the effect diagram after the microwave rotary irradiation and the radio frequency rotary irradiation are synchronized or superimposed on heating, that is, the superimposed diagrams of FIG. 8 and FIG. 11. After synchronizing or superimposing the heat, precise temperature measurement is carried out by nuclear magnetic temperature measurement and optical fiber temperature measurement technology. When the temperature in the central area reaches about 42.5° C., the fat layer is about 2 cm still in the low temperature area, about 38° C., and the temperature of each tissue of the inner side of the fat layer is maintained at a range of 40˜42° C., showing a state of uneven temperature distribution.

[0106] FIG. 11 shows a heating effect diagram after the global radiation ring 33 continues to slowly supplement heat and conduct heat. The entire heating circle section is slowly supplemented by reducing the power of microwave and radio frequency. After a period of slow supplementation, the temperature is gradually increased while the temperature difference between the tissues is eliminated, and the temperature is slowly increased after a certain period of time. The temperature is finally uniform and maintain a constant temperature after reaching 43° C. for certain time to consolidate the effect of thermotherapy.

[0107] S2: The intelligent control unit 4 slows down the heating speed by adjusting the power of the microwave rotary heating mechanism and the capacitive radio frequency rotary heating mechanism to supplement the heat of the body membrane thermotherapy area, and it takes no less than 10 minutes for each temperature rise of 1° C.;

[0108] In this embodiment, the pair of capacitor plates 36 and the microwave magnetron 37 are slowly supplemented with heat at the third set power and the fourth set power, for example, 100 W.

[0109] S3: After the temperature of the body membrane thermotherapy area rises to 42° C., the intelligent control unit 4 further controls to slow down the heating speed, combined with the heat conduction between adjacent tissues of the body membrane, so that the internal temperature of the body membrane is gradually uniform and accurate to 43° C. and maintained the body temperature balance; the intelligent control unit 4 maintains a relative constant temperature in the thermotherapy area for 30˜60 minutes based on the real-time temperature measurement data, under the premise of ensuring that the human body temperature resistance limit is not exceeded;

[0110] S4: In the above steps, the internal temperature data of the body membrane obtained with the help of optical fiber temperature measurement technology is the reference system, and the non-invasive in the body precise temperature measurement is achieved through the use of nuclear magnetic thermal imaging technology. The temperature measurement data is transmitted to the intelligent control unit 4 to accurately control the body membrane heat in real time. The temperature of the treatment area does not exceed the tolerance limit. Specifically, the step (S4) is performed through the following steps.

[0111] S401: Use the nuclear magnetic thermal imaging device to scan each temperature hot point in a certain temperature range (20˜80° C.), and establish a temperature field distribution map library for each temperature corresponding to the hot point.

[0112] The temperature field distribution map library must be composed of an unlimited number of continuous hot point thermal imaging data within a set interval. In actual operation, according to the accuracy requirements, a large number of hot point thermal imaging data statistics can be used to generate a thermal imaging information data map library composed of discontinuous hot spots, as a standard reference system, ensures that the temperature distribution map obtained by each nuclear magnetic thermal imaging device scans has no excessive deviation.

[0113] Further, in the temperature field distribution map library, the thermal imaging map data information has a one-to-one correspondence with its temperature value, which can be represented by two-dimensional coordinates.

[0114] S402: Obtain the temperature field distribution map of each hot spot in the patient's thermotherapy area (the composition of important hot spots can be selected according to the accuracy requirements) through the scanning of the nuclear magnetic thermal imaging device.

[0115] The temperature field distribution map includes thermal imaging information and location information of each hot point in the thermotherapy area (important hot points can be selected according to the accuracy requirements). The image information is a computer language containing temperature information, and the location information can use the form of three-dimensional coordinates.

[0116] S403: Use the optical fiber temperature measuring device to use non-invasive technology to obtain the temperature of several key points in the accessible part of the human body thermotherapy area as the temperature calibration point.

[0117] Further, the sensing optical fiber is non-invasively guided into the gastrointestinal tract, trachea, bladder, uterus, ear chamber and other tissue cavities in the patient's treatment area from the anus, mouth and nose, urethra, or ear canal, so as to avoid direct minimally invasive surgery of the human body and other forms of temperature measurement fiber into the human body to cause trauma.

[0118] Further, the temperature calibration point and its temperature reference include accurate temperature data and location information. The temperature calibration points obtained by the sensing optical fiber have corresponding points in the temperature distribution map, and the changes of the temperature values of both of them often lead to the same error in the same direction due to the change of objective factors.

[0119] S404: Combining the temperature field distribution map library obtained by scanning in step S401, calculate the temperature field distribution map obtained in step S402 to obtain the scanning temperature data of each hot spot in the thermotherapy area, and according to the temperature data of the temperature calibration point as the reference standard, the calculated scanning temperature data of each point is used for error correction, and the accurate temperature data of each hot spot in the thermotherapy area is obtained.

[0120] For example, if the precise temperature of point A on the sensing fiber measured by the optical fiber temperature measuring mechanism 2 is assumed to be 40° C., the position of the magnetic resonance scan of point A in the temperature field distribution map is point A′, which is compared with the temperature field distribution map library. The scanning temperature is 39.4° C., and the error correction value of the two is +0.6° C. If the position in the temperature field distribution map is point B′, the corresponding scanning temperature is 39.9° C., then the accurate temperature after error correction at this point is 40.5° C.

Embodiment 2

[0121] In this embodiment, the heating method of microwave combined with capacitive radio frequency rotary irradiation still uses the global irradiation ring 33 to heat the human body. The global irradiation ring 33 is provided with a pair of capacitor plates 36 and a pair of capacitor plates 36. Microwave magnetrons 37 are arranged at intervals in the circumferential direction. A pair of capacitor plates 36 is used for radio frequency heat transmission, and the frequency can be selected in the range of 5 MHz˜200 MHz. The microwave magnetron 37 is used for microwave heating, and its frequency can be selected from 300 MHz to 3000 MHz. In step S101, the two pairs of capacitor plates 36 are heated with the first and second set powers, such as 800 W, 300 W, and the two microwave magnetrons 37 are heated with the third and fourth set powers, such as 500 W, 200 W, and the temperature of center area and the muscle layer under the fat layer are the limit temperature points for temperature calibration. In step S102, the two pairs of capacitor plates 36 and the two microwave magnetrons 37 are both set to a low power, such as 80 W, to slowly supplement heat.

[0122] Based on the above heating parameters, steps S1˜S4 in Embodiment 1 are performed to implement the global heating of the body. As a consequence, not only the body surface, but also the deep organs can be accurately and easily heated, realizing accurate high heat and blanching throughout the body. The content of steps S1˜S4 will not be repeated here.

[0123] In the above global heating method, the heating parameters need to be selected by the physician according to human body constitution.

Embodiment 3

[0124] The present disclosure also provides a microwave radio frequency global irradiation thermotherapy instrument, as shown in FIG. 15, including a translational heat-preservation bin 1, a temperature measuring mechanism 2, a global irradiation unit 3, and an intelligent control unit 4.

[0125] The translational heat-preservation bin 1 includes a bin body 11, a bin holder 12 and a head holder 13. The bin body 11 includes a head protection bin 111 and a trunk support bin 112.

[0126] The bin body 11 is horizontally and slidably supported on the bin holder 12 and is driven by a drive mechanism provided in the bin holder 12. After the bin body 11 passes through the temperature measuring mechanism 2 and the global irradiation ring 3 in turn, the head protection bin 112 is supported on the head holder 13.

[0127] The temperature measurement mechanism 2 is used for real-time measurement of the temperature of any part of the human body section, and includes a nuclear magnetic thermal imaging device for collecting a temperature field distribution map of the human body section and an optical fiber temperature measurement device for temperature measurement at a temperature calibration point.

[0128] The temperature measurement method of the temperature field distribution map is as follows: first, the sensor fiber of the fiber optic temperature measuring device is introduced into the human esophagus, stomach or intestine through the mouth, nose or anus in a non-invasive manner. The sensor fiber can accurately measure the point temperature value of the path, take these points on the sensing fiber as temperature calibration points, and then scan the cross-section of the human body by the nuclear magnetic thermal imaging device to obtain the temperature field distribution map. Since the temperature calibration points are also in the thermal imaging scanning range, using the temperature of these calibration points as a reference, and the temperature value of each point in the thermal imaging range can be obtained in real time by comparing the temperature difference according to the temperature field distribution map.

[0129] As shown in FIG. 16, the global irradiation unit 3 includes a global irradiation ring 33, a microwave rotary heating mechanism, a capacitive radio frequency rotary heating mechanism, a rotating mechanism, and an annular phantom 5 (not shown in FIG. 16). The rotating mechanism includes a holder 31, a rotating drum 32, a driving roller 34, and a plurality of supporting rollers 35. The rotating drum 32 is placed on the holder 31 and supported by a number of supporting rollers 34, and is driven to rotate by the driving roller 33 to drive the global irradiation ring 33 to rotate.

[0130] The global irradiation ring 33 is provided with one or more microwave magnetrons 37 of the microwave rotary heating mechanism and one or more pairs of capacitive plates 36 of the capacitive radio frequency rotary heating mechanism. The capacitive plate 36 and the microwave magnetron 37 are arranged at intervals in the circumferential direction of the torus.

[0131] The microwave magnetron 37 is used for microwave heating, and its frequency can be selected in the range of 300 MHz˜3000 MHz. The other microwave magnetron 37′ has the same frequency range and can choose microwave devices with different powers. The capacitor plate 36 is used for radio frequency diathermy, and its frequency can be selected in the range of 1 MHz˜300 MHz, and the high frequency band realizes non-skin contact heating. The other capacitor plate 36′ can be eccentrically arranged to solve the problem of weak heat accumulation in the middle layer.

[0132] The rotating mechanism is used to drive the global irradiation ring 33 to rotate or brake according to the control program.

[0133] The intelligent control unit 4 is used to control the rotation speed of the global radiation ring 33, the radio frequency and power of the capacitor plate 36 (36′), the microwave frequency and power of the microwave magnetron 37 (37′), and the feed location of the bin body 12.

[0134] In the translational heat-preservation bin 1 of the thermotherapy instrument, the base 31 drives the bin body 11 to feed, and the feeding position is controllable. The nuclear magnetic thermal imaging device can collect the temperature field distribution map of the human body section containing the optical fiber temperature probe, using the temperature measured by the optical fiber temperature probe in real time is used to display the temperature of any part of the cross section of the human body after temperature calibration of the temperature field distribution map. The global irradiation unit 3 has five modes: microwave static mode, microwave rotation mode, radio frequency static mode, radio frequency rotation mode, and microwave radio frequency combined mode for physicians to choose from.

[0135] This thermotherapy instrument uses the advantages of deep radio frequency heating to uniformly heat all points in the treatment area, and the radio frequency heating is rotary heating to avoid the overheating of the surface fat layer caused by radio frequency radiation, and it can focus the deep layer to high temperature, and use the feature of microwave selection heating to avoid the shallow fat layer to ensure that the fat will not overheat. The middle layer high temperature ring is formed by rotating radiation, and the middle layer inside the fat is heated by insufficient heat due to the radio frequency rotary radiation, and the heat is supplemented to achieve uniform heating. The frequency of radio frequency should be 1˜300 MHz, and the frequency of microwave should be 300˜3000 MHz. In addition, the capacitive radio frequency rotary heating mechanism utilizes an annular phantom matched with capacitive radio frequency rotary irradiation to compensate for irregular defects of the human body to form a regular cylinder, which facilitates the capacitive radio frequency rotary heating mechanism to closely adhere to heat.

[0136] In one embodiment, on the global irradiation ring 33, one or more pairs of capacitor plates 36 and a number of microwave magnetrons 37 are arranged in different planes, that is, the ring surface on which one or more pairs of capacitor plates 36 are located and the ring surface on which the several microwave magnetrons 37 are located are partially or completely staggered on the central axis of the global irradiation ring 33 to avoid coplanarity.
