【Abstract】 PET is a radioactive tracer imaging technique used in medicine tostudy the uptake of a metabolic fluid which has been labelled with a positron emitting radionuclide. PET’s major strength is the ability to visualize and quantify the metabolic processes. The recent technical development in PET design,including detector, front end electronics, data acquisition system, image reconstruction and PET construction design, is introduced, and the future prospect of development is described, in this paper.更多还原
