Abstract

We have developed a SPECT gamma photon ray-tracing method based on the SolidWorksTM stereolithography (.STL) file format that models penetration, scatter, and fluorescence in the design work flow[1]. With this powerful tool, now we are able to model various kinds of novel SPECT systems including those with moving collimators. In this work, the configuration of a rotating-slit aperture in combination with a 1D or 2D detector is revisited, and the method of virtual pinhole synthesis is discussed. Our preliminary simulation results indicate an increasing advantage with decreasing aperture size due to the relatively larger sensitivity of slit apertures compared to real pinhole apertures.
