Abstract: According to an embodiment, there is provided that processing circuitry configured to determine a first radiation timing at which a subject is irradiated with an X-ray, based on information on motion of an object in X-ray image data, the information on motion being calculated by the X-ray image data, the X-ray image data being associated with an electrocardiographic waveform of the subject, and repeatedly irradiate the subject with an X-ray at the first radiation timing per cycle of the electrocardiographic waveform of the subject.

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: 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.
