In this study, we have developed and evaluated a UTE-
and R2*-based segmentation method for performing
attenuation correction and compared it to a published
method. Our results show that the proposed method
outperforms the existing method in the accuracy of
bone/air segmentation as well as in the accuracy of
simulated PET images reconstructed using the attenuation
maps derived from the segmentation methods.
