Reducing Multiplexing Artifacts in Multi-Pinhole SPECT with a Stacked Silicon-Germanium System: a Simulation Study

In pinhole SPECT, multi-pinhole collimators can increase sensitivity but may lead to projection overlap, or multiplexing, which can cause image artifacts. In this work we explore whether a stacked-detector configuration with a germanium and a silicon detector, used with (123)I (27–32, 159 keV), wher...
