Provided is a radiation phase-contrast imaging device capable of assuredly detecting a self-image and precisely imaging the internal structure of an object. According to the configuration of the present invention, the longitudinal direction of a detection surface of a flat panel detector is inclined with respect to the extending direction of an absorber in a phase grating. This causes variations in the position (phase) of a projected stripe pattern of a self-image at different positions on the detection surface. This is therefore expected to produce the same effects as those obtainable when a plurality of self-images are obtained by performing imaging a plurality of times in such a manner that the position of the projected self-images on the detection surface varies. This alone, however, results in a single self-image phase for a specific region of the object. Therefore, according to the present invention, it is configured such that imaging is performed while changing the relative position of the imaging system and the object.

A breast imaging apparatus includes a radiation generation unit configured to generate radiation and a radiation detection unit configured to detect radiation irradiation from the radiation generation unit and can rotate the radiation generation unit and the radiation detection unit in a state in which they face each other. Imaging is performed in a state in which a body part (breast) of an object to be imaged is sandwiched by a pressing panel on a first side of the breast imaging apparatus. In addition, imaging is performed while rotating the radiation generation unit and the radiation detection unit in a state in which the body part (breast) of the object to be imaged is inserted between the radiation generation unit and the radiation detection unit from a second side opposite to the first side of the breast imaging apparatus.

The disclosure relates to a system and method for medical imaging. The method may include: move, by a motion controller, a phantom along an axis of a scanner to a plurality of phantom positions; acquire, by a scanner of the imaging device, a first set of PET data relating to the phantom at the plurality of phantom positions; and store the first set of PET data as an electrical file. The length of an axis of the phantom may be shorter than the length of an axis of the scanner, and at least one of the plurality of phantom positions may be inside a bore of the scanner.

A surgery system includes a mechanical hub, an anatomy support structure coupled to the mechanical hub, a first moveable support structure, and an imaging system comprising a source element and a detector element. The imaging system is coupled to the mechanical hub via the first moveable support structure such that the source element and the detector element are repositionable relative to the anatomy support structure. The surgical system also includes a second moveable support structure coupled to the mechanical hub and a surgical instrument coupled to the mechanical hub via the second moveable support structure.

A radiation detecting apparatus detects radiation transmitted through a subject. The radiation detecting apparatus includes a hardware processor. The hardware processor detects rotation angles of the radiation detecting apparatus with respect to two mutually perpendicular axes to output angle information, and also detects an orientation of the radiation detecting apparatus. The hardware processor outputs the angle information for the detected orientation.

A scanning system for three-dimensional imaging comprises a bench, a gantry frame, a light source, a sensor and a control unit. The bench is to support a subject to be scanned. The gantry frame is movably mounted at a lateral side of the bench. The light source is movably mounted on the gantry frame so as to emit a light for a radiographic purpose. The sensor is movably mounted at a side of the bench, by opposing to the subject with respect to the bench, so as to receive the light emitted from the light source. The control unit is electrically coupled with the gantry frame, the light source and the sensor so as thereby to perform motion controls upon the gantry frame, the light source and the sensor.

An X-ray device includes a C-bracket having a radiation detector rotatably mounted on the C-bracket. The radiation detector may be rotated by a motor drive. The axis of rotation is perpendicular to the detector surface. The motor drive is a torque motor that includes a stator and a rotor. The radiation detector is coupled to the rotor.

An X-ray device has a detector which is arranged on a mobile unit and is assigned to a first positioning unit. An X-ray source is arranged on an arcuate second positioning unit. The positioning of the first and second positioning units can be matched to one another in the course of their movements. The first positioning unit has at least one articulated arm and the second positioning unit has a first and a second arc-shaped positioning element. The first and second positioning units are arranged separately from one another on a movable unit.

The present invention provides a latching mechanism for an x-ray tube assembly comprising a rotary plate, a first spring-loaded latch and a second spring-loaded latch which are disposed diametrically. The rotary plate comprises a first receiving portion and a second receiving portion spaced from each other by 90°. The first spring-loaded latch configured to be pressed removably into the first receiving portion to lock the x-ray tube assembly in a first position and the second spring-loaded latch is configured to be pressed removably into the second receiving portion to lock the x-ray tube assembly in a second position. According to the present invention, it is possible tomake manufacturing tolerance control and assembly of the x-ray imaging system much simpler and easier.

During the generation of a panoramic x-ray recording, the use of semi-transparent x-ray screens allows the patient's x-ray exposure to be reduced when partial x-ray images are created, in spite of relatively large overlapping areas between the partial x-ray images.
