Abstract: An X-ray diagnosis apparatus includes: an X-ray; an X-ray detector; processing circuitry configured to generate an X-ray image based on the detected X-rays, and causes a display to display the X-ray image; a first operator that receives an operation of inputting a central position for a displayed image to be displayed on the display; and a second operator that receives an operation of inputting a field-of-view size of the displayed image in a stepless manner. The processing circuitry is configured to change the field-of-view size of the displayed image in response to an operation at the second operator, while the central position of a current displayed image is being maintained.

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.
