Abstract
An X-ray CT apparatus according to an embodiment includes: an X-ray detector of photon counting type including a plurality of detection elements and a voltage supply device configured to supply the detection elements with a voltage for reading out electric charges accumulated in the detection elements irradiated with X-rays; and processing circuitry configured to identify a target element from among the detection elements based on information acquired in advance, the target element causing a large current to flow through a circuit between the target element and the voltage supply device and compensate for a change of the voltage supplied from the voltage supply device to the target element.
