I am using ITK and SimpleITK in Python. I would like to register multiple slices with known relative orientation into a volume. I found this page with similar topic https://itk.org/pipermail/community/2014-September/007124.html
However I don’t have orthogonal slices and I tried the method of pasting the slices into a volume anyway but the error is high and for the proposition to “modify a similarity metric to accept multiple images” I just didn’t find any ITK documentation or example from which to deduce how to do that…
Plus has an implementation of merging slices in arbitrary orientations into a volume. It is based on VTK, not ITK, but you could probably use it as a building block since it is open source too.
