Question about `mri_convert`
sravan953 opened this issue · comments
Hello,
The readme states:
Before deploying our model you need to standardize the MRI scans. Use the following command from FreeSurfer
mri_convert --conform <input_volume.nii> <out_volume.nii>
The above command standardizes the alignment for QuickNAT, re-samples to isotrophic resolution (256x256x256) with some contrast enhamcement. It takes about one second per volume.
Assuming FreeSurfer is not available, could you please elaborate on the pre-processing steps?
- What exactly does it mean to standardize alignment?
- Is the contrast enhancement necessary?
Obviously, QuickNAT is implemented with Freesurfer. so I think you must use Freesurfer's mri_convert function.
Furthermore, This paper is NOT focused on MRI image's preprocessing.
