Abstract
A photon counting X-ray image diagnosis apparatus according to an embodiment includes an X-ray tube, a photon counting X-ray detector, and processing circuitry. Based on detection data sets obtained by performing a phantom imaging process using of mutually-different acquisition parameter sets by which X-rays radiated onto a phantom are detected by the X-ray detector, the processing circuitry identifies a boundary condition defining a range of acquisition parameter sets corresponding to a pileup occurrence. The processing circuitry sets a margin range based on the boundary condition. The processing circuitry generates acquisition parameter sets included in a range obtained by adding the margin range to the range of the acquisition parameter sets. The processing circuitry generates calibration data for a pileup correction based on detection data sets obtained by using the acquisition parameter sets.
