Fig. 2From: Evaluating a radiotherapy deep learning synthetic CT algorithm for PET-MR attenuation correction in the pelvisExample PET images reconstructed using the sCTAC (a), MRAC (b) and CTAC (c) attenuation correction maps. The threshold GTV contour is shown in purple, blue and red, respectively. Zoomed in pictures of the same GTVs are shown in (d). The patient was selected as having the sCTAC and MRAC \({\mathrm {SUV}}_{\max}\) differences closest to the mean differencesBack to article page
