Project Description


It is one of the goals of the QIICR project to enable interchange of quantitative imaging research results using DICOM. In this project we will be testing and refining the tools developed for communicating datasets produced by the QIICR Iowa DBP using DICOM SR, SEG and RWV modalities, to accompany the publicly available QIN-HeadNeck collection of PET/CT datasets earlier released by the Iowa group.

Approach, Plan

  • Evaluate the earlier developed tools, identify missing functionality
  • Verify functionality on Christian's laptop
  • Prepare publicly available illustrative datasets


  • Improved conversion routines (see https://github.com/QIICR/Iowa2DICOM)
    • several patches for dcmtk-seg were submitted to address blocking issues
    • converter routines updated (SEG and SR encoding routines)
    • bootstrap conversion script added
  • Verified the conversion pipeline is working on Christian's laptop
  • Testing input dataset (PET series, NRRD segmentations and quantitative indices extracted from segmentation-derived regions) and derived DICOM objects (DICOM SEG multi-segment segmentations, RWVM encoding of SUV map, DICOM Structured Report (SR) for encoding of region of interest measurements) released in public domain. Disclaimer: we continue working on verifying and improving these objects, but they are good initial examples of DICOM capabilities.
