SPECT System Modeling and Simulations

In any Single Photon Emission Computed Tomography (SPECT) scanner, an accurate model of its response is crucial to correctly predict its performance and to get the best reconstruction outcome. This is why we work on improving current methods for analytical modeling of SPECT systems, in particular for the geometrical collimator response in the innovative scanner designs which we develop in our group, which can have quite complex geometries.

On the other hand, we also use statistical software packages (Monte Carlo-based simulation software GATE) that allow us to perform realistic simulations of our system. It is more difficult to use these for the reconstruction itself, but we use them to produce realistic projection data to reconstruct and validate our analytical modeling.
