    摘要： An image obtainment unit obtains plural radiographic-images generated by arranging plural storable-phosphor-sheets in such a manner that at least portions of the sheets are overlapped with each other in an irradiation direction of radiation, by arranging a marker at a position to be detected by the plural sheets, and by detecting the radiation that has passed through a subject and the marker by each of the plural sheets. A first-information obtainment unit obtains first-information representing a distance between detection surfaces of the plural sheets. A second-information obtainment unit obtains second-information representing a magnification ratio of a second marker image of the marker included in a radiographic-image obtained by a second sheet with respect to a marker image of the marker included in a radiographic-image obtained by a first sheet of the plural sheets. A distance calculation unit calculates, based on the first and the second information, a radiation-source-to-image-surface distance.

    摘要： According to an embodiment, an X-ray CT system includes a gantry, a first couch, a second couch, a carrier unit, and control circuitry. The gantry includes an X-ray tube, an X-ray detector, and an operation unit. The first couch is arranged in a first room. The second couch is arranged in a second room. When carrying the gantry to the first room, the carrier unit arranges the gantry in an orientation in which the front side of the gantry faces the first couch. When carrying the gantry to the second room, the carrier unit arranges the gantry in an orientation in which the back side of the gantry faces the second couch. The control circuitry controls the direction of the tilt movement of the gantry in accordance with the room where the gantry is arranged.

    摘要： A mobile X-ray apparatus for medical examination includes an apparatus for producing X-ray images having a digital Radiography detector positioned at a first spatial position, an X-ray tube assembly positionable at a second spatial position relative to the first spatial position, sensor(s) for providing the first spatial position and/or the second spatial position, a control unit for receiving the first and/or the second spatial position(s) from the at least one sensor and for controlling the first or second spatial position for alignment of the X-ray tube assembly with the detector based on the first and second spatial positions, a drive wheel, a base, optionally an elevating column, and a telescopic arm which is rotatable into a direction perpendicular to a driving direction of the base. The apparatus is controllable to drive along a patient table and/or the X-ray tube assembly is height adjustable in front of a wall stand, for alignment.
