Operating system: mac OS Catalina
Slicer version: 5.0.3
I am trying to combine 3MRI scans of a forearm/wrist taken at different table positions into a single image volume. They are all of the same patient and I currently have three NIFTI files: hand to wrist (distal), wrist to mid-forearm (middle) and midforearm to elbow (proximal). There is some overlap between the image volumes. I have been trying to use Mikebind’s StitchVolumes Extension to combine the three volumes into a single image of the forearm.
Sadly I have not had much luck - the images seem to be stitching in the wrong order regardless of the order in which I enter them into the extension. I also seem to be losing some of each volume. I have tried to use fiducial registration wizard to apply transforms to ensure images are in the correct location, but this does not seem to work either.
Any help anyone can provide would be much appreciated
Hi all, managed to overcome this problem. In case anyone finds this problem in future, the issue is that i wasn’t shifting the locations of the different scans properly, which needs to be done in slicerIGT’s fiducial registration wizard, before stitching together in StitchVolumes. Otherwise, the volumes will just overlie each other at the same point in space.
