Abstract
According to one embodiment, an X-ray diagnostic apparatus includes an X-ray tube, an X-ray detector and processing circuitry. The X-ray tube exposes an X-ray toward an object. The X-ray detector acquires two X-ray detection data sets by counting X-ray photons, having transmitted the object, in at least two X-ray energy bands depending on a K absorption edge of an X-ray absorber taken into the object. The processing circuitry is configured to input information to specify the X-ray absorber, set the at least two X-ray energy bands based on the input information to specify the X-ray absorber and generate at least one frame of X-ray image data by data processing including subtraction processing of the two X-ray detection data sets. The X-ray absorber has been depicted in the at least one frame of the X-ray image data.
