Gamma ray camera system

The invention discloses a gamma ray camera system, and relates to the technical field of radiation detection. The gamma ray camera system comprises a shell, a collimator, a semiconductor detector and a rear-end electronics circuit, the collimator, the semiconductor detector and the rear-end electronics circuit are arranged in the shell, the collimator is located at the front end of the semiconductor detector, and the semiconductor detector is electrically connected with the rear-end electronics circuit; rays emitted by the radioactive substance enter the shell and enter the semiconductor detector through the collimator to form induction current, and the induction current passes through the rear-end electronics circuit and then outputs a digital signal. The gamma ray camera system has the advantages of being small in size and convenient to carry. 一种伽马射线照相机系统，涉及辐射探测技术领域。该伽马射线照相机系统包括壳体以及设置于壳体内的准直器、半导体探测器和后端电子学电路，准直器位于半导体探测器的前端，半导体探测器和后端电子学电路电连接；放射性物质发出的射线入射至壳体内并经过准直器入射至半导体探测器后形成感应电流，感应电流经过后端电子学电路后输出数字信号。该伽马射线照相机
