Abstract: An x-ray diagnosis apparatus according to an embodiment includes an x-ray tube holder, a supporter, an ultraviolet ray, a contact portion detector, and an irradiation controller. The x-ray tube holder holds an x-ray tube. The supporter movably supports the x-ray tube holder. The ultraviolet ray emitter is disposed to the x-ray tube holder and emits ultraviolet rays. The contact portion detector detects a contact portion touched by a subject of detection, which is at least one of a subject of examination and an examination technician. The irradiation controller controls the support to move the x-ray tube holder to a position corresponding to the contact portion, and controls the ultraviolet ray emitter to emit the ultraviolet rays toward the contact portion.

Abstract: According to one embodiment, an X-ray diagnostic apparatus includes an X-ray movable diaphragm and processing circuitry. The X-ray movable diaphragm limits an irradiation field of an X-ray. The processing circuitry sets an FOV size related to the irradiation field, sets a virtual field of view having the FOV size, the virtual field of view being able to include an outside region of an X-ray detection region and at least a part of the X-ray detection region, and controls the X-ray movable diaphragm so as to apply the X-ray to a common region between the virtual field of view and the X-ray detection region.

Abstract: An X-ray apparatus includes a light emitting unit, input interface circuitry, and processing circuitry. The light emitting unit includes a light source. The input interface circuitry inputs an X-ray condition. The processing circuitry controls an emission state of the light emitting unit to change to one of at least three states based on the X-ray condition.

Abstract: When distance compute unit 81 received the instruction of the moving destination at the center of the exposure field 4a from center transfer operation unit 74, calculates the moving amount. Operating information processing unit 8 sends beam-limiting control unit 62 the calculated moving amount. Upside beam-limiting control unit 63 to right side beam-limiting control unit of beam-limiting control unit 62 makes the moving amount at the center of the exposure field 4a prescribed-times ((H1/H2) times in FIG. 3), calculates the moving amount of each diaphragm blade unit 51 in the upper part, the lower side, and the left part and the right part respectively.

Abstract: A bed apparatus includes a bed, a bed lifting unit that lifts the bed, and a bed stop position control unit that controls the bed lifting unit such that the bed stops at a position out of the maximum stroke according to a predetermined stop condition.

Abstract: A medical image radiography apparatus includes a radiography system for taking a medical image of a subject, a supporting mechanism for supporting the radiography system in various radiography positions, a memory unit for storing a plurality of radiography positions, together with their order relation, as sequential automatic positioning data, and a controller for controlling the supporting mechanism on the basis of the sequential automatic positioning data in order to change a radiography position sequentially. In this manner, the plurality of radiography positions are stored, together with their order relation, as the sequential automatic positioning data. When taking a radiograph, the radiography position is sequentially changed in accordance with the sequential automatic positioning data. As a result, the operability concerning a change in the radiography position is improved more than in the conventional case wherein a preset button is repeatedly selected.
