4D Maximum A Posteriori Reconstruction in Dynamic SPECT Using a Compartmental Model-Based Prior
A 4D ordered-subsets maximum a posteriori (OSMAP) algorithm for dynamic SPECT is described which uses a temporal prior that constrains each voxel’s behavior in time to conform to a compartmental model. No a priori limitations on kinetic parameters are applied; rather, the parameter estimates evolve...
