Abstract: An X-ray diagnostic apparatus of an embodiment includes an input interface, and processing circuitry. The input interface accepts an input operation performed by an operator. The processing circuitry identifies a period in which periodic movement is small in an X-ray irradiation area. The processing circuitry determines irradiation start timing of an X-ray according to the period. The processing circuitry controls to perform X-ray irradiation of a relatively high dose in the determined irradiation start timing on condition that the input operation is being continued.

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.

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.
