Abstract
According to one embodiment, a flexible wedge filter is arranged between an X-ray tube and an examinee to attenuate a dose according to an X-ray from the X-ray tube. The flexible wedge filter has a plurality of filter moduleshaving a configuration capable of individually changing an X-ray transmission path length in an X-ray shielding material. The PCCT gantry controller individually operates the plurality of filter modules such that a dose according to an X-ray incident to an X-ray detector from the X-ray tube via the examinee is distributed substantially uniformly in spatial.
