I have been able to use Segment Comparison and got the maximum, 95th, and median distance just like you described. However, is there a way to extract all the distances between the two segments instead of just the three metrics above? I want to assess if the treatment zone has achieved enough margin around the pre-treatment tumor, so the minimum distance between these two segments is more important for this assessment.
I’ve been searching for awhile, and I found a link on github
[https://github.com/SlicerRt/SlicerRT/blob/master/SegmentComparison/Logic/vtkPolyDataDistanceHistogramFilter.cxx]
It seems like Segment Comparison module does calculate all the distances but only the max, 95th, and median are shown in Slicer. I have only been using Slicer for a couple weeks but I’m very much interested to learn more. Would you point me in the direction of extracting the distance histogram or just the minimum distance value?
