Abstract: According to an X-ray diagnostic apparatus, an X-ray tube radiates X-rays. An X-ray collimator adjusts an irradiation region of the X-rays. An X-ray detector includes a first detector and a second detector having a smaller detection area than a detection area of the first detector. The X-ray detector is able to detect the X-rays radiated with the first detector and the second detector at the same time. Processing circuitry generates a synthesized image obtained by synthesizing a first X-ray image generated based on an output from the first detector that detected the X-rays radiated in the irradiation region adjusted, and a second X-ray image generated based on an output from the second detector that detected the X-rays radiated in the irradiation region adjusted, the synthesized image having an image size corresponding to an aspect ratio of the irradiation region. The processing circuitry causes a display to display the synthesized image.

Abstract: According to one embodiment, an X-ray diagnosis apparatus includes an X-ray tube, a diaphragm mechanism, an X-ray detector, image generating circuitry, a display, a first interface, a second interface, and processing circuitry. The processing circuitry controls the diaphragm mechanism and the X-ray tube according to the operation to the first interface so that the X-rays are radiated to a first radiation range, and controls the diaphragm mechanism and the X-ray tube according to the operation to the second interface so that the X-rays are radiated to a second radiation range. The processing circuitry controls the display so that the first display area displays the X-ray images sequentially generated according to radiation of the X-rays, in parallel with the radiation.

Abstract: An operation device comprises a detector configured to detect an operation on a virtual switch by an operator to operate an X-ray irradiation in an X-ray diagnosis apparatus, wherein the virtual switch is virtually set at a position settled relatively with respect to the operator and output circuitry configured to output a detection result of the operation detected by the detector to the X-ray diagnosis apparatus to be operated. This device eliminates the need for looking away from a display monitor every time the operator operates the X-ray diagnosis apparatus.
