摘要 本文简要介绍了近年来SPECT准直器几何设计和对应图像重建计算方法的最新进展以及当前图像重建研究的一些热点。 In this short note we give a brief introduction to the recent development in the design of SPECT collimator geometry and its corresponding reconstruction algorithms. Moreover, we review some hot fields of recent studies on SPECT image reconstruction problem. (
