为使X—CT得到优质的图像，确保探测器正常工作是非常必要的。本文以fi2020CT为例，介绍对探测器进行检测的几种方法。一、探测器的结构固体探测器（SolidStateDetector）主要由（发光）晶体、光电池、前置放大器和外面的保护屏蔽罩所组成。晶体吸收X线后所发射出的可见光由光?
For the X-CT to get a good image, it is very necessary to ensure the normal operation of the detector. This article uses fi2020CT as an example to introduce several methods to detect the detector. First, the structure of the detector The solid state detector (SolidStateDetector) is mainly composed of (luminous) crystal, photocell, preamplifier and external protective shield. After the crystal absorbs X-rays, the visible light emitted by the light?
