On the imaging reconstruction of DHC, new algorithms using iterative reconstruction that based on the ordered subsets estimation maximization(COSEM) has been developed for coincidence imaging that improved the effect of imaging.

• 由于双探头符合线路在图像处理方面采用了符合探测的预先分组最大期望值图像重建(COSEM)方法(迭代重建法)代替了常用的滤波反投影法(FBP),使图像效果有了明显改善。
