A structure for positioning a body part includes a support base, and a shell frame having an inner surface configured to a shape of the body part. The shell frame is further configured to ride upon the support base, or upon a carriage that further rides upon the support base, to enable a pitch and/or a roll of the shell frame to be adjusted relative to the support base.

A medical navigation system is provided. The medical navigation system includes a computing device having a processor coupled to a memory, a wireless communication component and a display for displaying an image. The medical navigation system further includes a sensor module attached to a medical device. The sensor module includes a housing for housing components of the sensor module and for attaching to the medical device, a processor housed in the housing, a memory coupled to the processor, a wireless communication component coupled to the processor, a battery coupled to the processor, and a sensor coupled to the processor. The sensor generates a signal to be transmitted wirelessly via the sensor module wireless communication component and receivable by the computing device wireless communication component, the signal representing movement of the medical device.

Provided is a head positioning frame that includes an upright rod, a base ring, and a head nail. The upright rod includes at least two connecting portions, and at least one of the at least two connecting portions is made of an insulating material, such that the upright rod, the base ring, the head nail, and a head to be positioned are incapable of forming an electrical circuit loop.

A system for immobilization of a patient body part for radiotherapy applications includes a device having at least one flanged support member which is mounted to a fixation surface. The device can receive and retain at least two sheets. A first sheet covers the anatomical contours of a first area of a body part. A second sheet covers the anatomical contours of a second area of the body part which is not covered by the first sheet. The system supports the immobilized body part free from the fixation surface by the two sheets and the device.

The present invention relates to a respiratory gating system for a patient using a natural breathing method during radiation therapy, and a method for emitting radiation thereby. A respiratory gating system allowing radiation to be emitted by orienting to the position, which varies according to a patient's breathing, of a subject on which treatment is to be carried out, comprises: a breathing respirator for allowing the patient's respiration amount to be measured; external markers to be respectively adhered to triangulation points outside the human body of the surrounding region of the subject, of the patient, on which treatment is to be carried out; an image diagnosis device for imaging the region of the subject of the patient on which treatment is to be carried out, by photographing the same; and a computer program programmed so as to calculate, as position coordinates, the change in position of the subject on which treatment is to be carried out, according to the respiration amount measured by the computed tomography equipment and the each external marker, through a triangulation method and dual polynomial equations, and to transmit the position coordinates, which changes in real time, to radiation therapy equipment, wherein radiation is emitted by the respiratory gating system, and there is an effect of further increasing the accuracy and stability of the entire radiation therapy result by tracking, in real time, the movement of an organ, which is the subject on which treatment is to be carried out according to breathing, through a respiratory gating system which uses natural breathing rather than a breathing method through the training of the patient.

The present relates to a positioning and shaping shell manufacturing method for manufacturing a positioning and shaping shell comprising a positioning step consisting in positioning and supporting a target body portion with a transparent body shaper in a predetermined position on a positioning board presenting at least one transparent portion permitting scanning through it, an image acquisition step consisting in a target body portion surface scan imaging also via the transparent portion of the board and said transparent body support, a software computing step where the acquired image data are sent and processed in a processing unit, and a producing step consisting in producing a 3D positioning and shaping shell model via additive or subtractive manufacturing method based in the processed image data.

An immobilization system, especially for use on the human head and neck area, is described in various embodiments. The system may include a bite block immobilization system having a bite block with a dental interface releasably engageable with a plurality of teeth of a patient, and a retention mask. The dental interface releasably engages the teeth of a patient and allows very highly accurate repositioning during multiple procedures. In some embodiments, the bite block may have an integral bite block airway passage, allowing a patient to have unobstructed breathing both during molding of the retention mask and during subsequent use of the system, and may include a tongue diverter, that may, by way of example only and not limitation, be used to divert the tongue away from a therapeutic radiation beam. Steps for utilizing the system are further described.

A mask fixing apparatus, a mask component and a radiotherapy device are provided. The mask fixing apparatus includes: a frame, being configured to fix a mask, the frame being U-shaped having an inner boundary line and an outer boundary line, an opening of the frame fitting a neck of a patient, the inner boundary line of the frame being determined based on a periphery of a head of the patient, and the outer boundary line of the frame being determined based on a treatment cavity or an anti-collision cover in the treatment cavity; and a back-head support, being configured to support a back-head of the patient, and being connected with the frame to jointly carry the head of the patient, the inner surface of the back-head support fitting the back-head of the patient, and the outer surface of the back-head support being a curved surface having a preset curvature.

A medical system may comprise a stereo display and an input device. The medical system may also comprise a processor configured to generate a three-dimensional image of an anatomical object and cause the three-dimensional image of the anatomical object and a two-dimensional window to be displayed. The processor may also be configured to cause a position and an orientation of the two-dimensional window relative to the three-dimensional image of the anatomical object to be changed on the stereo display by manipulation of the input device. The processor may also be configured to define a cut-plane to indicate a two-dimensional slice of the three-dimensional image of the anatomical object. The processor may also be configured to cause the two-dimensional slice of the three-dimensional image of the anatomical object to be displayed. An orientation of the displayed two-dimensional slice may be different than an orientation of the cut-plane with the three-dimensional image.
