Key Investigators
- Steve Pieper, Isomics
- Andrey Fedorov, BWH
- Michael Onken, Open Connections / DCMTK
Project Description
Objective
- Review progress on DICOM Enhanced Multiframe Object support in DCMTK
- Segmentation Objects (see Iowa2DICOM)
- Diffusion Profiles
- Parametric Maps
- Ultrasound Objects
- Derived Objects
- Review the options for a dcm2dcm tool
- Convert legacy acquisitions to multiframe objects
- Correctly encode derived objects
Approach, Plan
- Try to build Slicer with latest DCMTK that includes Multiframe Object support
- Try simple programs to exercise API
Progress
- In-depth code and standard review during QIICR breakout session
- dcmseg (seg==Segmentation), dcmiod (iod==Information Object Definition), dcmfg (fg==Functional Groups) libraries explored
- prototype converters to/from nrrd for segentation objects
- Identified issues with multiframe MR import in slicer
- gdcm and dcmtk based readers in ITK cannot currently extract orientation/spacing from per-frame functional groups
- plan is to look at fixing itkDCMTKImageIO once the version of DCMTK has dcmiod and dcmfg integrated
- nearer-term a pydicom-based reader could be written for slicer DICOMPlugin
References
- There are several Slicer/ITK bugs related to improper handling of "21st Century DICOM" objects using legacy code designed for older objects.
