DAS DETECTOR AND X-RAY COMPUTED TOMOGRAPHY SCANNER

摘要

A DAS detector, in which an X-ray detector and DAS are integrated in order to prevent the DAS from breaking down due to X-rays, is provided. An X-ray computed tomography scanner equipped with the DAS detector is also provided. The DAS detector comprises an X-ray detector, a circuit board, a DAS, and multiple X-ray shielding plates. The X-ray detector detects X-rays, and produces electrical signals corresponding to the detected X-rays. The circuit board is joined to the X-ray detector, and has wiring patterns for extracting the electrical signals from the X-ray detector. The DAS is joined to the circuit board, and has electronic components for processing the electrical signals. Each X-ray shielding plate is disposed on the circuit board in such a manner that the electronic components are not exposed to the X-rays that are transmitted through the X-ray detector. A portion of the wiring patterns is positioned between multiple X-ray shielding plates.
