Bias atlas images showing the voxel-by-voxel relative difference between MRAC and CTAC based PET images in non-TOF and TOF reconstruction. Non-TOF reconstructions are represented with: a bulk, c cuboid and e template method. TOF reconstructions are represented with b bulk, d cuboid and f template method. Local overestimations are seen with the bulk method whereas overestimations are reduced with the proposed methods and with TOF
