摘要

A test device for isotopic gamma-ray imaging, which consists of an isotope gamma-ray source, a CdZnTe gamma-ray spectrometer and other auxiliary equipment, is studied here. Compared with the conventional X-ray, the isotope gamma-ray, which is utilized in this project, has its own advantages in imaging. Furthermore, with a room-temperature high-energy-resolution CdZnTe detector and a modem imaging processing technique, this device is capable of effectively suppressing the background and gaining more information, thus it can obtain a better image than conventional X-ray devices. In the experiment of PCB imaging, all soldered points and chip components are sharply demonstrated.
