摘要
本文着重介绍近几年PET/CT中PET的技术进展。新晶体材料的应用使得PET/CT在分辨率和灵敏度等方面有了显著提高,飞行时间技术(TOF)改善了PET数据的信噪比,最新型的HD PET技术则让PET获得了全视野一致的高清图像。文章最后简要描述了目前商业PET/CT的临床应用。
This study introduced the recent PET technology development of PET/ CT. The application of new scintillator significantly improved the resolution and sensitivity of PET/CT. the technology of time of flight （TOF） increased the signal- to-noise ratio of PET data. and the streamlined high-defination （HD） technology offered uniform resolution across the entire field of view and enhanced the quality of images. At last. the clinical practice of current PET/CT was briefly described.
