The invention provides for a medical apparatus (100, 300, 400) comprising a subject support (102) configured for moving a subject (106) from a first position (124) to a second position (130) along a linear path (134). The subject support comprises a support surface (108) for receiving the subject. The subject support is further configured for positioning the subject support in at least one intermediate position (128). The subject support is configured for measuring a displacement (132) along the linear path between the first position and the at least one intermediate position. Each of the at least one intermediate position is located between the first position and the second position. The medical apparatus further comprises a camera (110) configured for imaging the support surface in the first position. Execution of machine executable instructions 116 cause the a processor (116) controlling the medical apparatus to: acquire (200) an initial image (142) with the camera when the subject support is in the first position; control (202) the subject support to move the subject support from the first position to the second position; acquire (204) at least one intermediate image (144) with the camera and the displacement for each of the at least one intermediate image as the subject support is moved from the first position to the second position; and calculate (206) a height profile (150, 600, 604) of the subject by comparing the initial image and the at least one intermediate image. The height profile is at least partially calculated using the displacement. The height profile is descriptive of the spatially dependent height of the subject above the support surface.

Apparatuses (devices, systems) and methods for shielding (protecting) surroundings around periphery of regions of interest located inside objects (e.g., patients) from radiation emitted by X-ray systems towards the objects. Apparatus includes: at least one radiation shield assembly including a support base connectable to an X-ray system radiation source or detector, and a plurality of radiation shield segments sequentially positioned relative to the support base, thereby forming a contiguous radiopaque screen configured for spanning around the region of interest periphery with a radiopaque screen edge opposing the object. Radiation shield segments are individually, actively controllable to extend or contract to selected lengths with respective free ends in directions away from or towards the support base(s), for locally changing contour of the radiopaque screen edge. Applicable for shielding (protecting) medical personnel, and patients, from exposure to X-ray radiation during medical interventions or/and diagnostics.

An N-M tomography system comprising: a carrier for the subject of an examination procedure; a plurality of detector heads; a carrier for the detector heads; and a detector positioning arrangement operable to position the detector heads during performance of a scan without interference or collision between adjacent detector heads to establish a variable bore size and configuration for the examination. Additionally, collimated detectors providing variable spatial resolution for SPECT imaging and which can also be used for PET imaging, whereby one set of detectors can be selectably used for either modality, or for both simultaneously.

A method for tracking the position of a person in an environment, such as a medical room, relative to a medical device is presented. The method comprises identifying the position of a medical device in the environment, providing a mobile device in the vicinity of a person in the environment, the mobile device configured to follow movement of the person in the environment, and identifying the position of the mobile device in the environment by using at least one stationary device. Further, the method comprises using a processor to process data relating to the position of the mobile device in the environment to obtain an expected position of the person in the environment, data relating to the position of the medical device in the environment, and data relating the expected position of the person in the environment to obtain an expected relative position of the person with respect to the medical device.

Disclosed herein are an X-ray detector having impact resistance, and an X-ray imaging apparatus including the same. An X-ray detector for detecting X-rays irradiated from an X-ray source includes a case having at least one opening and a sensing panel configured to convert the X-rays irradiated from the X-ray source into an electrical signal. A frame detachably inserted into the inside of the case through the at least one opening. The frame includes a body on which the sensing panel is disposed and a plurality of legs extending from the edges of the body in a first direction of the X-ray detector. A plurality of buffer members disposed between the plurality of legs and the case and in close contact with the plurality of legs and the case while surrounding a plurality of surfaces of each of the plurality of legs.

Disclosed is a C-shaped arm X-ray apparatus, comprising a C-shaped arm translation assembly (1), a support column (2), a base (3), a balancing weight (4) and an adjusting apparatus. One end of the support column (2) is connected to the base (3), and the other end of the support column is slidably connected to the C-shaped arm translation assembly (1). The balancing weight (4) is in sliding connection with the base (3). The adjusting apparatus is connected to the balancing weight (4), and when the C-shaped arm translation assembly (1) moves in a first direction, the adjusting apparatus enables the balancing weight (4) to move by a preset distance in the direction opposite to the first direction such that the gravity center of the C-shaped arm X-ray apparatus can be maintained at a preset position. The stability of the C-shaped arm X-ray apparatus can be guaranteed by adjusting the position of the balancing weight (4) by means of the adjusting apparatus.

A method for adjusting a medical device is provided. The method includes obtaining an initial trajectory of a component of the medical device. The initial trajectory of the component includes a plurality of initial positions. For each of the plurality of initial positions, the method further includes determining whether a collision is likely to occur between a subject and the component according to the initial trajectory of the component. In response to the determination that the collision is likely to occur, the method further includes updating the initial trajectory of the component to determine an updated trajectory of the component.

A breakaway hinge for a portable medical device, such as a cart-borne ultrasound system, enables the movement of an access door in other dimensions than the hinge access. The hinge includes a sliding magnet which attaches to a fixed magnet, and a hinge pin, all acting together to allow the door to open, to shift the door away from the hinge, and to detach the door as desired.

An imaging apparatus for use with an imaging device in order to image a subject. The imaging device includes an annular gantry having an opening and a table to accommodate the subject or a portion thereof for imaging. The imaging apparatus includes a platform and a positioning device. The imaging device is mounted to the platform. The annular gantry is in a fixed position relative to the platform. The table is horizontally displaceable relative to the annular gantry. The positioning device supports the platform and is configured to horizontally displace the platform relative to a supporting surface for the subject. The positioning device is configured to position the platform with the imaging device in at least one operational state in such a way that, during a relative movement of the table with respect to the annular gantry, the table remains stationary relative to the supporting surface.

An apparatus for Digital Imaging in the Head Region of a Patient includes an X-ray source and an X-ray sensor, supported on a rotary arm supported on a structure by a motor driven translation and rotation means. The rotary arm is provided with adjustment means for varying the distance between the source and the sensor. A control unit, that controls the source, the sensor, the adjustment means, and the translation and rotation means Collision detection means provided in the source and sensor detect a possible collision of the source and/or sensor with the patient during the motion of the source and/or sensor and the control unit responds to such detected possible collision.
