摘要

探测器的串扰噪声会对探测器的信噪比以及高能工业CT的图像质量产生很大的影响。本文利用EGSnrc程序模拟估算了CdWO4探测器模块的串扰噪声

并初步分析比较了影响探测器模块串扰噪声的各种因素。对在实际中选用和设计探测器模块有一定的指导意义

同时为利用软件修正探测器串扰噪声提供了理论计算参数。

Abstract

The signal-noise ratio of detectors and the image quality will be affected by the detector cross-talk noise. In this paper we use EGSnrc to research the cross-talk noise in the CdWO4 detector module

and analyze various factors which can bring about the cross-talk noise. The work will facilitate the selection of detector module and offer some parameters for the correction of cross-talk noise with software.
