X-RAY COMPUTED TOMOGRAPHY APPARATUS AND PHOTON COUNTING CT APPARATUS

摘要

A gantry includes two X-ray source rings and a detector ring. Each X-ray source ring includes a plurality of X-ray sources arrayed circumferentially. The detector ring is provided next to the X-ray source ring and includes a plurality of X-ray detectors arrayed circumferentially. Each of the plurality of X-ray detectors detects X-rays from the X-ray source ring. A data collection circuit collects raw data corresponding to the intensity of the detected X-rays. A reconstruction unit reconstructs the collected raw data into a CT image based on digital data.

1. An X-ray computed tomography apparatus comprising:
two X-ray source rings arrayed along a central axis, each of the two X-ray source rings including a plurality of X-ray sources arrayed on a circumference; a single detector ring provided between the two X-ray source rings and including a plurality of X-ray detectors arrayed on a circumference, each of the plurality of X-ray detectors detecting X-rays from the two X-ray source rings; a data collection unit configured to collect digital data corresponding to an intensity of the detected X-rays; and a reconstruction unit configured to reconstruct a CT image based on the digital data.
