The present invention provides an X-ray transceiving component for a CT imaging apparatus, comprising one or more bulb devices and a plurality of detector devices. The one or more bulb devices are configured to emit quadrate-tapered or fan-shaped X-ray beams. The plurality of detector devices are configure to receive the quadrate-tapered or fan-shaped X-ray beams emitted by the one or more bulb devices, each of the quadrate-tapered or fan-shaped X-ray beams comprising X-rays passing through a scanning field of view. Note that the plurality of detector devices are configured to receive X-rays passing through different areas within the scanning field of view, the one or more bulb devices are micro-focus bulb devices, and the plurality of detector devices are flat panel detectors or photoelectric coupling detectors. The present invention can greatly improve a resolution of CT imaging, increase imaging efficiency, and realize low-dose diagnosis in the case of ensuring that the scanning field of view is sufficient.

A portable XRF analyzer includes a hand shield to substantially block x-rays from impinging on a hand of a user. The portable XRF analyzer includes a heat sink over an x-ray source and a heat sink over an x-ray detector. The heat sinks are separated from each other by a thermally insulative material.

An X-ray CT apparatus according to an embodiment includes processing circuitry. The processing circuitry is configured to detect X-rays that have passed through a subject by using a detector and to acquire projection data on a basis of a detection result. The processing circuitry is configured to obtain position information of a highly X-ray absorbent member in the body of the subject. The processing circuitry is configured to derive information about transmission paths of the X-rays in accordance with a processing effect of an artifact reducing process performed on the highly X-ray absorbent member, on the basis of the position information of the highly X-ray absorbent member.

A system and corresponding method for detecting one or more high-atomic-number elements in a patient includes a Bremsstrahlung x-ray source that produces x-rays in an energy spectrum including an energy of at least 160 kiloelectron-volts (keV), a filter configured to absorb the x-rays in a region of the energy spectrum, and a collimator configured to receive the x-rays and output a collimated x-ray beam to be incident on a patient. The system and method can also include one or more collimated, energy-resolving x-ray detectors to detect fluorescent radiation emitted from the one or more high-atomic-number elements in the patient in response to the collimated x-ray beam incident on the patient. An alternative x-ray source can include a radioactive isotope. Scanning of the x-ray beam may also be performed. Embodiments enable practical clinical, in vivo measurements of lead in bone.

An improved configuration of a mobile-type radiographic image pickup device reliably stops on a flat path without play. More specifically, the prevent invention stops reliably on an inclined path. Where a carriage accelerates regardless of that fact that a deceleration control unit has begun to restrict the movement of the carriage, a brake control unit causes a brake device to operate. According to the present invention, if the carriage accelerates regardless of the fact that a deceleration control unit has begun to restrict the movement of the carriage, the brake device is promptly operated, and prevents concern regardless of the application of an instruction to stop the carriage which is travelling on an incline, and prevents the carriage from running for a long period to time.

A radiation image capturing apparatus is provided. The apparatus comprises an image capturing unit configured to acquire a radiation image, the image capturing unit being provided with a plurality of receptor fields for acquiring irradiation information of radiation concerning an integrated dose of radiation entering during irradiation with radiation, and a selection unit configured to select a receptor field, of the plurality of receptor fields, which is used by a user. The selection unit changes an upper limit of the number of receptor fields, of the plurality of receptor fields, which are used for one image capturing operation depending on when the radiation image capturing apparatus is attached to a stand to which the radiation image capturing apparatus can be attached and when the radiation image capturing apparatus is detached from the stand.

A multi-modality imaging system allows for selectable photoelectric effect and/or Compton effect detection. The camera or detector is a module with a catcher detector. Depending on the use or design, a scatter detector and/or a coded physical aperture are positioned in front of the catcher detector relative to the patient space. For low energies, emissions passing through the scatter detector continue through the coded aperture to be detected by the catcher detector using the photoelectric effect. Alternatively, the scatter detector is not provided. For higher energies, some emissions scatter at the scatter detector, and resulting emissions from the scattering pass by or through the coded aperture to be detected at the catcher detector for detection using the Compton effect. Alternatively, the coded aperture is not provided. The same module may be used to detect using both the photoelectric and Compton effects where both the scatter detector and coded aperture are provided with the catcher detector. Multiple modules may be positioned together to form a larger camera, or a module is used alone. By using modules, any number of modules may be used to fit with a multi-modality imaging system. One or more such modules may be added to another imaging system (e.g., CT or MR) for a multi-modality imaging system.

An intra-oral X-ray imaging system according to an embodiment of the present disclosure includes an intra-oral X-ray sensing device being shaped in such a manner as to be hand-gripped by an user and performing X-ray imaging within an oral cavity through X-ray radiation, a charging connection deck having a structure where the intra-oral X-ray sensing device is accommodated therein and is chargeable, the charging connection deck being electrically connected to the intra-oral X-ray sensing device when the intra-oral X-ray sensing device is accommodated, and an X-ray image generation and display device being electrically connected to the charging connection deck, image-processing X-ray data resulting from the X-ray imaging, generating an X-ray image as a result of the image-processing, and displaying the generated X-ray image for a user's viewing, wherein the X-ray image generation and display device receives the X-ray data resulting from the X-ray imaging, through the charging connection deck.
