摘要
文中介绍了高能显像技术的发展和应用，介绍了三种高能准直法，并进行了比较和预测。
High Energy Positron Imaging (HEPI) is a new technology. The idea of positron imaging can be traced back to early 1950′s. HEPI imaging is formed by positron emitter radionuclide produced by cyclotron, such as 15 O, 13 N, 11 C and 18 F, which are most abandant elements in human body. Clinical applications of HEPI have been witnessed rapidly in recent years. HEPI imaging can be obtained by both PET and SPECT, namely high energy collimation imaging, Mdecular Coincidence Detection (MCD) and positron emission tomography.
