I have a question about a problem I am facing.
I am currently working on MRI images with a slice thickness which is either 2 mm (in some patients) or 3 mm (in some other patients). And I would like to extract 2D features.
My question is:
- Should I resample the images on the z-axis in order to get a common thickness? (e.g. specifying “resampledPixelSpacing: [1, 1, 2.5]”).
- Or should I not resample the z-axis? (e.g. specifying “resampledPixelSpacing: [1, 1, 0]”), therefore accepting the fact that the z dimension can differ from patient to patient?
Thank you in advance!
