Abstract:Quantitative PET attenuation correction (AC) for cardiac PET/CT and PET/MR is a challenging problem. We propose and evaluate an AC approach that uses coincidences from a relatively weak and physically fixed sparse external source, in combination with that from the patient, to reconstruct
-maps based on physics principles alone. The low 30 cm
3
volume of the source makes it easy to fill and place, and the method does not use prior image data or attenuation map assumptions. O… Show more
