Project Description

Objective

• Evaluate different options for converting from DICOM-seg/NIFTI/nrrd (mask) to DICOM-RT (contours) and back.
• Compare performance of Slicer RT/plastimatch/others.

Approach, Plan

• Develop a test set with range of appearance of structures
  • overlapping
  • donuts

Progress

• Creates python script (based on Slicer RT) for converting contours to label maps (thanks Csaba!)
• Reporting module provides conversion from label map to DICOM-SEG
• Plastimatch has DICOM-RT import export
• Will test full roundtrip conversions using QIN lung segmentation challenge datasets
• Started creating a library of test cases with known issues (donuts, overlapping structures etc)
• Will also create synthetic datasets
