断层屏蔽SPECT中角度函数的引入,使探测器收集到的粒子计数在不同的角度表现出有极大值,该极大值随点源的位置而变化,它包含了丰富的信息.论文在点源/均匀圆柱体水模型下推导了极大值出现的方程,并用数值计算和蒙特卡洛模拟进行了分析和讨论.

Introducing the angle function to slice collimator SPECT, It is found that the counts of the de-tectors achieve the maximum value in different angles, which change with the position of the point source and contain a wealth of information. In the paper, point source/uniform water cylinder model is used to derive the equation of the maximum value, with a further analyzing and discussion using the numerical calculation and Monte Carlo simulation.
