Operating system: Windows
Slicer version: 4.11 and 4.13
Expected behavior: ROI to match with CT image size
Actual behavior: ROI is in wrong location and of the wrong size
Hi, I am working on a project which requires me to compare the ROIs created by different software and compare them on LifeX to perform radiomics analysis. The ROIs I have exported from CERR and MICE toolkit all match perfectly in LifeX, however that exported from Slicer is rotated and of the wrong size and resolution. I have used the following instructions to export the ROI in both Nifti and NRRD format: Segmentations — 3D Slicer documentation
The data set I am using is the following: data_sets/ibsi_1_validation/dicom/STS_001/CT at master · theibsi/data_sets · GitHub
As you can see, the original CT image dimensions are 198x202x59 whereas that of the mask exported from Slicer are 239x248x264. Are there any specific setting I could use to obtain a binary mask that has the same size as the CT matrix?
Many thanks for your help!
