X-RAY COMPUTED TOMOGRAPHY DEVICE, AND PHOTON COUNTING CT DEVICE

摘要

The purpose of the present invention is to achieve high-speed imaging. A gantry (10) is provided with an X-ray source ring (13) and a detector ring (17). The X-ray source ring (13) is provided with a plurality of X-ray sources (11) which are arranged circumferentially. The detector ring (17) is disposed next to the X-ray source ring (13), and is provided with a plurality of X-ray detectors (15) which are arranged circumferentially. Each of the plurality of X-ray detectors (15) detects X-rays from the X-ray source ring (13). At least one wedge filter (21) is provided to the inner peripheral side of the X-ray source ring (13). A filter support mechanism (23) supports the at least one wedge filter (21) such that the at least one wedge filter (21) is capable of rotating around a rotational axis. A filter drive unit (25) drives the filter support mechanism (23). An imaging control unit (67) controls the filter drive unit (25) such that the at least one wedge filter (21) rotates around the rotational axis in synchronization with the generation of X-rays from the X-ray source ring (13).
