  Authors: Siyuan Han, Xin Yu, Yibin Zhang, Lei Zhao, Liyan Zhao, Huiping Zhao, Jinyong Tao, Jianfeng Xu, Qiyu Peng

  Abstract:

  To achieve a PET system that simultaneously offers high sensitivity, high spatial resolution, improved signal to noise ratio (SNR), and depth of interaction (DOI) measurement, we propose and implement a high DOI resolution PET detector based on a 1.5 × 1.5 × 20 mm³ BGO crystal array. In addition, we introduce a vertical line-source irradiation DOI calibration method, which enables...
