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.

Abstract: According to one embodiment, an X-ray diagnostic apparatus includes processing circuitry. The processing circuitry sets a plurality of ROIs in a first X-ray image. The processing circuitry calculates a statistical value for each ROI based on a plurality of values of pixels included in each ROI, thereby obtaining a plurality of statistical values. The processing circuitry acquires a threshold value for each statistical value. The processing circuitry determines a set of X-ray conditions relating to capturing of a second X-ray image subsequent to the first X-ray image based on the statistical value and the threshold value relating to each ROI.

Abstract: An X-ray diagnosis apparatus according to an embodiment includes a processing circuitry. The processing circuitry is configured: to determine a region corresponding to a target object in an X-ray image, on the basis of the X-ray image; to calculate a statistical value related to the region, on the basis of a plurality of pixel values included in the region; and to set an X-ray condition related to generating X-rays, on the basis of the statistical value.

Abstract: In one embodiment, an X-ray diagnostic apparatus can communicate with a controller configured to operate a catheter robot capable of moving an inserted device within the object and comprises a display and processing circuitry. The display is configured to display at least one fluoroscopic image of an object. The processing circuitry is configured to receive a control signal indicating a content of an operation on the catheter robot from the controller, acquire a plurality of fluoroscopic images of the object by irradiating the object with X-rays, control X-ray irradiation to the object, cause the display to display the plurality of fluoroscopic images to be sequentially acquired when the X-ray irradiation is performed, generate a plurality of reproduced images based on the plurality of fluoroscopic images acquired before a stop of the X-ray irradiation and cause the display to display the plurality of reproduced images when the X-ray irradiation is stopped.

Abstract: According to one embodiment, an X-ray diagnosis apparatus includes a table, an imaging unit, and processing circuitry. The table includes a table top on which a subject is placed. The imaging unit includes an X-ray tube which emits X-rays to the subject and an X-ray detector which detects the X-rays. The processing circuitry detects contact between an object and at least one of the imaging unit and the table. The processing circuitry executes control to display contact position information relating to a position in contact with the object based on a detection result.
