Embodiment 1

[0067] In order to improve the problems of low ray conversion rate of existing detectors and limited application range of existing detection systems, the designer has carried out various researches. After research, it is found that it is difficult to realize the ray conversion rate by changing the structure of the existing detectors. Therefore, the designer turned to look for other detectors with higher ray conversion rate. After many investigations and verifications, it was found that the CZT detector has better performance. The CZT detector uses a new type of semiconductor material, which can directly The radiation energy is converted into an electrical signal, the conversion efficiency is high, and the required radiation dose is small. In addition, the study also found that compared with existing detectors such as scintillator detectors, CZT detectors not only can work well at room temperature, but also have higher energy resolution and spatial resolution; in addition, the d...
