ScanSim: A tool for simulating optical-CT imaging.


Journal Article

A software tool has been developed that can simulate image formation in a variety of optical-CT scanning configurations. The formalism of the simulation is introduced, including two main modes: a diverging point source mode, and a converging broad beam mode. Preliminary results are presented for scanning Presage dosimeters in both modes and immersed in refractive media of widely varying refractive index (RI), including air, water, and a fully matched medium. Pronounced differences in the edge artifacts and accuracy of reconstructed coefficients is observed. The ScanSim software is shown to be a useful tool to investigate and quantify many aspects of optical-CT image formation, including reducing dependence on matching fluids.
