Dear people of the SCT community,
Does anyone have tips for improving the results of CSF segmentations using propseg? The cord segmentations for my dataset look pretty good already, but CSF segmentations seem pretty rough at times. I’ve fiddled with changing parameters such as -max-deformation and the like, as advised in the documentation for helping the cord segmentation but I’ve not noticed much improvement on the CSF segmentations.
Segmentation holds pretty well in C1 and C2, but at C3 it begins to show signs of trouble (see above, excuse the low quality image) as the spinal canal transitions towards a less rounded shape.
It is possible that my images are not ideal (we are using images that have been cropped and resampled with JIM - because we wished to recycle some measurements that had been done upon this set) and I may be pushing the algorithm - still, any advice will be appreciated.
