摘要

介绍并讨论了与核医学成像有关的Cd、Z%Te探测器的实验参数。利用早期原型Cd,JqTe探测器阵列成像仪和核医学成像平行孔准直仪模拟人类患者的观察结果，获得了甲状腺幻像的图像。幻影中充满了Tc-99m溶液。结果与现代商用Anger相机在相同条件下获得的图像进行了比较。Cd，-J%的成像仪被发现显示出分辨率和对比度至少等于那些愤怒的相机。

CdZnTe Detector Arrays For Nuclear Medicine Imaging

Experimental parameters of Cd,,Z%Te detectors relevant to nuclear medical imaging are presented and discussed. An image of a thyroid phantom was acquired with an early-stage prototype Cd,JqTe detector array imager using conditions to emulate observations in a human patient and a nuclear medicine imaging parallel-hole collimator. The phantom was filled with a Tc-99m solution. Results were compared with an image obtained from a modern commercial Anger camera under the same conditions. The Cd,-J%Te imager was found to exhibit resolution and contrast at least equal to those of the Anger camera.
