We had previously reported a simulation study on a multi-pinhole collimator (MP) having lead vertical septa which could provide improved angular sampling and enlarged imaging field of view (FOV) compared to low energy high resolution parallel-hole collimator (LEHR) using same size detector. The aim of this study was to develop a miniature SPECT to verify the performance of the proposed MP. A detector...
The aim of this study is to design a detector module employing multi-pinhole collimator which could be utilized in various SPECT systems. Monte Carlo simulations using Geant4 application for tomographic emission (GATE) were performed to estimate the performance of various multi-pinhole collimators and compared to that of low energy high resolution (LEHR) parallel-hole collimator. The simulated detector...
