A support structure and an imaging component are provided in an imaging system. The imaging component comprises a port extension that frames an opening for x-ray emission. The support structure comprises a recess for receiving the port extension, the recess also framing an opening for x-ray transmission. The imaging system may be a computed tomography (CT) imaging system, x-ray diagnostic system, or other imaging system.

A first positional information derivation unit derives three-dimensional positional information of at least one target point of a target structure in a subject as first positional information. A second positional information derivation unit derives three-dimensional positional information of at least one feature point on an insertion structure inserted to the target structure in the subject as second positional information. A display control unit displays a positional information screen indicating a positional relationship between the target point and the feature point on a display unit.

A nuclear medicine tomography system including: a detector carrier; a detector carrier housing including an inner space; a plurality of detector units, coupled to the detector carrier, each detector unit comprising: a detector camera; a cooling channel which guides air to the detector camera from the inner space; an exhaust channel which guides air from the detector camera to the inner space; a heat pump configured to cool air within the inner space.

According to one embodiment, a medical image processing apparatus includes processing circuitry. The processing circuitry is configured to obtain time changes of concentrations of a contrast agent, based on at least X-ray contrast image data; generate a gray scale or a color scale by assigning a change in pixel value for at least one period, to a period shorter than a period from an initial time to an ending time of the time changes of the concentrations of the contrast agent; and generate blood vessel image data according to the gray scale or the color scale. The blood vessel image data have pixel values corresponding to times at which the concentrations of the contrast agent become a specific condition.

A multiple frames imaging system is disclosed with capability of differential x-ray exposure of different input areas of an image intensifier or other x-ray detector. Collimators are provided to control the amount of radiation in various regions of the image and image processing is provided to provide the display of images of different qualities. Motion methods are provided to move the collimators to produce optimal image frames.

Novel and advantageous systems and methods for performing X-ray imaging by using an X-ray source with source grating functionality incorporated therein are provided. An electron beam can be electromagnetically manipulated such that the X-ray source emits radiation in a pattern that is the same as if the radiation had already passed through a source grating.

The subject of this invention is a system and method for distortion adaptation for use with an imaging grid alignment apparatus (analogue or digital) and method of intra-operative use for joint replacements, spine, trauma fracture reductions and deformity correction and implant placement/alignment. The system provides for real time dynamic position tracked distortion-adaption grid.

Clamping devices that are used to assist with the operation of small, portable x-ray devices are described in this application. In particular, this application describes clamping devices used to connect a portable X-ray device to an external support structure. The clamping devices contain a cradle configured to support a portion of a C-arm of a portable x-ray device, the cradle comprising a restraint configured to fit in an upper opening of the C-arm, a mounting plate configured to support a bottom portion of the portable x-ray device, a registration insert configured to mate with an opening in the bottom portion of the portable x-ray device, the registration insert also configured to move laterally along the mounting plate, a connecting member configured to move laterally along the mounting plate, and an attachment device configured to move the connecting member and the registration insert to attach the portable x-ray device to the cradle. Using such a clamping device allows the portable x-ray device to be quickly and easily attached to, and detached from, the external support structure by the average person using only a single hand, while also preventing the portable x-ray device from accidentally being removed from the support structure. Other embodiments are described.

The present technology relates to a radiation detection apparatus that makes it possible to obtain a projection image of a radiation in a short period of time. The radiation detection apparatus includes a scintillator that emits scintillation light in response to incidence of a radiation, a pixel substrate on which a plurality of pixels each of which photoelectrically converts the scintillation light and outputs a pixel signal according to a light amount of the scintillation light is disposed in an array, a detection circuit substrate that includes an A/D (Analog to Digital) conversion unit for A/D converting the pixel signal and is stacked on the pixel substrate, and a compression unit that compresses digital data outputted from the A/D conversion unit. The present technology can be applied, for example, to an X-ray imaging apparatus that detects an X-ray to perform imaging and so forth.

Radiation treatment is delivered to a patient by positioning the patient such that a radiation beam is delivered to a lesion within the patient along a beam-delivery path while securing a diagnostic imaging device about the patient such that the diagnostic imaging device does not intersect the beam-delivery path. Radiation therapy is simultaneously delivered along the beam-delivery path while diagnostic images are obtained using the imaging device.
