New statistical models for randoms-precorrected PET scans,ompensates in mean for accidental coincidences but destroys the Poisson statistics. We propose and analyze two new approximations to the exact log-likelihood of the precorrected measurements, one based on a “shifted Poisson” model, the other based on saddle-point approximations to the measurement pr

Deformation for image guided interventions using a three component tissue model,s often not valid due to tissue deformation. Most non-rigid registration algorithms, such as those used for atlas matching, provide a smooth deformation, which does not model the characteristics of different tissues accurately since, for example, bone will appear to deform. We suggest that a physica
