Abstract:
1. A system that generates an attenuation correction (AC) map template for correcting attenuation in a nuclear image caused by accessories in a nuclear scanner field of view during a nuclear scan, including: a processor that: generates an AC map template of an accessory from transmission data acquired during a nuclear scan of the accessory; receives scan data of the accessory from a nuclear scanner with a transmission source; determines an average linear attenuation coefficient (LAC) value from a distribution of a histogram of transmission data values; and assigns the average LAC value to the accessory when generating the AC map template; stores the AC map template to a memory; and iteratively generates a unique AC map template for each of a plurality of different accessories, the templates being stored in a template library in the memory for recall and use by an operator.
