引言随着核子医学的发展,借助于放射性分布图象法,对人体各脏器的静态或动态功能的研究,日渐增多。伽玛照相机是核子医学诊断仪器中的重要设备之一,它不仅可以快速地拍摄脏器的静态图片,而且更为重要的是能作脏器动态功能分析和照相。因此,在国外得到迅速地发展,近年来,我国已先后 INTRODUCTION With the development of nuclear medicine, the research on the static or dynamic functions of various internal organs of human beings has been increasing with the aid of the radiation distribution image method. Gamma camera is one of the important equipment in nuclear medical diagnostic equipment. It not only can quickly take still pictures of organs, but more importantly, it can do dynamic function analysis and photography for organs. Therefore, it has been rapidly developed in other countries. In recent years, our country has followed
