We describe an evaluation of the accuracy of the estimated average μ-value within patients from MR derived μ-maps. Recently, a more optimal initial attenuation image or μ-map estimate in TOF-MLAA reconstruction has been proposed for hybrid PET/MR imaging. The proposed initial μ-map estimate is an image of the object filled with the average μ-value, and the proposed Initial Average Mu-value approach...
Truncation compensation (TC) is critical in MR based attenuation correction of quantitative PET image reconstruction in clinical whole-body PET/MR systems. The purpose of this study is to quantitatively evaluate the impact of MR image truncation on PET image reconstruction and the performance of a newly developed TC technique, using Monte-Carlo (MC) simulation. The NCAT phantom was used to create...
