Fig. 5From: Accurate hybrid template–based and MR-based attenuation correction using UTE images for simultaneous PET/MR brain imaging applicationsComparison of PET images for the Test participant. Comparison of PET images for the Test participant (panel a) reconstructed with five different attenuation maps: PETref (column 1), PETUTE (column 2), PETUCL (column 3), PETsUTEcont (column 4) and PETsUTEfix (column 5). Comparison of corresponding normalized error (panel b) for the reconstructed PET data is depictedBack to article page
