Abstract

According to one embodiment, an X-ray diagnostic apparatus including processing circuitry. The processing circuitry is configured to cause an X-ray detector to read a signal in a non-destructive readout before termination of X-ray exposure, the signal being accumulated in an X-ray detection element; cause the X-ray detector to read the signal in a destructive readout after termination of X-ray exposure; acquire first projection data generated based on the signal read in the non-destructive readout and acquire second projection data generated based on the signal read in the destructive readout; estimate, based on the second projection data, a saturation region in which saturation is occurring; and replace a signal in the saturation region of the second projection data with a signal in the saturation region of the first projection data.
