I’m trying to do the N4 correction from open-source breast cancer MRI images: Single site breast DCE-MRI data and segmentations from patients undergoing neoadjuvant chemotherapy (Breast-MRI-NACT-Pilot) - The Cancer Imaging Archive (TCIA) Public Access - Cancer Imaging Archive Wiki
These images only show one side of the breast, when I want to do N4 on it by 3D-slicer, I can’t select the volume as input volume in Filtering > N4ITK MRI Bias Correction.
Then I transferred this series of DICOM images into NRRD format, and re-open it but I still couldn’t select it as input volume.
Then I tried to do it in python, but with the error:
Can anyone know how to solve this problem? You can download images from the above links and the “Sagittal-IR_3DFGRE” series was what I used.
