Determination of spatial resolution of plastic scintillation fib...

The spatial resolution of a position sensitive gamma-ray detector configuration based on plastic scintillation<BR>fiber array was measured using a Monte Car10 simulation method. Both point spread function and modulation transfer<BR>function (MTF) were presented. The factors that influence the spatial resolution were also discussed. The results of the<BR>simulation showed that the intrinsic spatial resolution was consistent with the size of the physical pixels and a few<BR>centimeters spatial res
