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.
