Abstract: An X-ray diagnosis apparatus according to an embodiment includes: an X-ray generator configured to emit X-rays; an X-ray detector having a detection surface parallel to a first direction and being movable in the first direction and in a second direction orthogonal to the first direction and parallel to the detection surface; and processing circuitry configured to set a plurality of imaging ranges touching each other on the basis of reference information, to cause the X-rays to be emitted from the X-ray generator to each of the plurality of imaging ranges while sequentially moving the X-ray detector, and to generate X-ray images respectively corresponding to the plurality of imaging ranges, on the basis of a detection signal resulting from the X-ray detector detecting the X-rays.

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.
