Abstract
An X-ray CT apparatus according to an embodiment includes processing circuitry. The processing circuitry is configured to detect X-rays that have passed through a subject by using a detector and to acquire projection data on a basis of a detection result. The processing circuitry is configured to obtain position information of a highly X-ray absorbent member in the body of the subject. The processing circuitry is configured to derive information about transmission paths of the X-rays in accordance with a processing effect of an artifact reducing process performed on the highly X-ray absorbent member, on the basis of the position information of the highly X-ray absorbent member.
