Dear Simple ITK Team,
We have two DICOM series and two RTSTRUCT masks which are converted into Nifti files. The original dimension of the nifti files are (256, 256, 216). We are trying to do registration and resampling to a new dimension (240, 240, 155) using Simple ITK library. When we are doing registration and resampling of the original nifti file into the new dimension (240, 240, 155), the masks are not matching with the tumor. There is mismatch of mask with the tumor image. The mask started 15 slices ahead than it appears in real tumor image.
When we are doing only resampling without registration using Simple ITK the generated mask and tumor in the images are matching.
Why we see such a discrepancy? Are we doing something wrong.
Your guidance will be highly appreciated.
