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 two X-ray source rings (13) and a detector ring (17). Each of the X-ray source rings (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 rings (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 rings (13). A data acquisition circuit (37) acquires raw data corresponding to the intensity of detected X-rays. A reconfiguration unit is used to reconfigure the acquired raw data into a CT image on the basis of digital data.
