Problems solved by technology

[0003] However, part of the X-rays incident on the detector will pass through the detector and be reflected back by the metal bracket on the back. This part of the X-rays may be reflected back to the electronic components or scintillators of the detector, causing interference to the signal and increasing noise. Therefore, it is easy to generate image artifacts and reduce the performance of the detector
[0004] Moreover, the existing X-ray detectors are generally designed based on Printed Wired Board (PWB). The thermal conductivity and strength of the printed circuit board material are limited, and sometimes it will be deformed due to pressure, heat, etc., which will affect the performance of the detector.

Abstract

The invention provides an X-ray detector for medical use. The X-ray detector comprises a bracket, wherein an X-ray-visible light conversion light, a photo-electric conversion layer and a printed circuit board are sequentially stacked on the bracket in the incidence direction of X ray; an X-ray absorbing layer is additionally arranged between the photo-electric conversion layer and the bracket; and the X-ray absorbing layer is used for absorbing the X ray reflected by the bracket.

Description

technical field [0001] The invention relates to the field of medical diagnosis, in particular to a medical X-ray detector. Background technique [0002] In X-ray medical diagnostic equipment, such as computer tomography (CT) equipment, X-ray detectors are used to detect X-rays passing through the human body, and the detection results are converted into image information for reference by doctors. [0003] However, part of the X-rays incident on the detector will pass through the detector and be reflected back by the metal bracket on the back. This part of the X-rays may be reflected back to the electronic components or scintillators of the detector, causing interference to the signal and increasing noise. Therefore, it is easy to generate image artifacts and reduce the performance of the detector. [0004] Moreover, the existing X-ray detectors are generally designed based on the Printed Wired Board (PWB), the thermal conductivity and strength of the printed circuit board ma...
