摘要
扼要描述单轨道锥形光SPECT中的失值问题以及Kriging统计估值方法。将Kriging方法用于三维圆盘模型的重建显像计算,使像的质量有明显的改善。
Missing data problem in single-orbit cone beam SPECT and Kjiging statistical estimation were described. Simulation study of Kriging method was carried out using a 3D slab phantom, resulting a better reconstruction image.
