Registration-based method for determining relative PET/MR left–right image orientation☆
2008
NeuroImage
Preserved Fulltext
We report on a quality control method for deducing the correct relative left-right orientation of a PET/MR image pair. ...
In this study, image registration was performed on the PET/MR image pair. The MR image was then reflected (left/right reversed) and the image registration was performed again. ...
