Hello,
I’ve been using PETSurfer for partial volume correction of PET images using the RBV option. I’m amending the parcellations/segmentations to add in extracortical areas of high PET signal (to prevent spill-in into the brain), and after adjusting the *ctab file this runs successfully.
However, I noticed the output resolution of the rbv.nii.gz image is the same as the input segmentation mask, not the expected 0.5mm iso. I’ve run a test incorporating the --rbv-res 0.5mm flag into the command line. The output rbv.nii.gz image is similar to the previous one (without the –rbv-res flag), again not as smooth as the typical output image.
Is it satisfactory to run the command with my amended seg image and the --rbv-res 0.5mm flag, and are there any additional recommendations for running PVC with an amended seg image?
Thanks very much,
Dan
