ABSTRACT:
A process for obtaining an attenuation map from a truncated transmission scan of an imaged object, by compensating for missing emission data as a result of truncation by using non-truncated emission data of the imaged object to derive “fill-in” emission data. The truncation-compensated emission data then is used to generate an attenuation map for correcting a reconstructed emission image for effects of attenuation.
