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: 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.

Abstract: According to one embodiment, an X-ray diagnostic apparatus includes processing circuitry. The processing circuitry is configured to acquire an X-ray image. The processing circuitry is configured to perform a determination as to whether or not a first trained model, to which the X-ray image is to be input, is adapted to the X-ray image, and if the determination indicates that the first trained model is not adapted to the X-ray image, apply image processing to the X-ray image so that the first trained model serves as an adapted model.

Abstract: An X-ray diagnostic apparatus according to an embodiment includes an X-ray tube, an X-ray detector, image generating circuitry, and processing circuitry. The X-ray tube emits X-rays. The X-ray detector detects X-rays emitted from the X-ray tube and transmitted through a subject. The processing circuitry receives a designating operation related a display mode for a target that is at least one of a region of the subject and an object inserted in the subject. In response to the designating operation, the processing circuitry changes the display mode of the target in an X-ray projection image that is based on a detection result of the X-ray detector, the display mode being changed based on three-dimensional medical image data related to the subject.
