Abstract :
We purpose a modified method for predicting the sensitivity performance by considering the tilted and translated pinhole apertures in a ring-type multi-pinhole collimation design. In addition to the tilted pinholes, we also applied a simple correction scheme for accounting various effects which cause the performance bias between the analytical and MC simulation
