Penetration, Scatter and Sensitivity in Channel Micro-Pinholes for SPECT: A Monte Carlo Investigation

Channel-edge pinhole designs have been proposed in order to reduce the penetration of gamma rays through the edge of the pinhole aperture. A characterization of penetration and scatter in the pinhole aperture metal can be used in the design of small animal SPECT collimators or for model based correc...
