Abstract
A system for generating a reconstruction filter for an imaging scanner comprises a model bank that includes a model for generating the reconstruction filter, a filter criteria bank that includes filter criteria for generating the reconstruction filter, and a filter generator that generates the reconstruction filter based on the filter model and the filter criteria. In one non-limiting instance, the model is based on minimizing a cost function that includes predetermined filter criteria such as image contrast. In another non-limiting instance, the cost function includes terms relating to spatial resolution, noise and a signal visual perception in the presence of noise.
