Patent ID: 8620053

Claim:
A method of generating a full image attenuation map of an object from a truncated image attenuation map of the object comprising the steps of: obtaining measured attenuated PET emissions data associated with the object using a plurality of detector pairs within an imaging system; obtaining data representative of a truncated image of the object using a second image modality; converting the data representative of a truncated image of the object to a truncated image attenuation map; an estimation module within the imaging system further performs the following steps: determining at least one missing portion of the truncated image attenuation map of the object; estimating image linear attenuation coefficients for the at least one missing portion of the truncated image attenuation map of the object; and generating the full image attenuation map of the object by combining the truncated image attenuation map and the estimated image linear attenuation coefficients for the at least one missing portion of the truncated image attenuation map of the object.
