Workflow schemes for coregistration of subject’s CT (a-d) and PET (e-h) to respective standard volumes. For CT, the 9 parameters from manual registration (B) were refined by SPM12’ coregistration module (d). For PET, both standard skull outlines and PET template were rescaled to the dimensions of the subject using the scaling factors from the CT coregistration. The 6 parameters from manual registration (f) were refined to transfer PET frames to the standard space (H) incorporating the scaling parameters from the CT coregistration.
