A PET Reconstruction Formulation that Enforces Non-negativity in Projection Space for Bias Reduction in Y-90 Imaging
Most existing PET image reconstruction methods impose a nonnegativity constraint in the image domain that is natural physically, but can lead to biased reconstructions. This bias is particularly problematic for Y-90 PET because of the low probability positron production and high random coincidence f...
