2012 Summer Project Week Breakout Session:Slicer DICOM

What

Catch up on DICOM projects.

Networking (Steve)

• Fix outstanding bugs
• Future work: CFINDSCP?

AIM/Structured Reporting/SEG (Andrey)

• Since January:
  • Slicer Reporting Module:
    • Slicer Infrastructure: ties to imaging data so things can go back to DICOM (requires volumes are DICOM)
    • Serialize slicer data structures to interoperable format (AIM)
  • DICOM Database integrated to support creation of correct AIM/SR documents
  • Standard Compliant Segmentation Objects (Tested against Syngo VIA)
    • Bitmasks per markup (can overlap)
    • Can associate markups with vocabularies
  • (Possibly augment slicer color tables with radlex terms)
  • Can be loaded in Syngo VIA, but does not display (Andrey is in contact with David Clunie and Siemens on this)
• Plans
  • Complete Reporting module with read/write support for Segmentation
  • Andrey will email segmentation object file to Larry Tarbox for testing
  • Integrate with DICOM Module
• Bundle nrrd data in private tags

RT (Greg/Andras)

• Since January (Andras)
  • Custom reader plugins
  • Structure Sets, RT Plan, Dose
• Some data stored in slicer MRML node attribues (dose units, scale)
• Deforming dose volumes loses dose information
  • User needs to specify dose units by hand
• Needs:
  • DICOM Export (dcmtk create by hand)
  • Connecting structure sets to the color tables

Diffusion and Timeseries

• Rely on DICOMToNRRD for diffusion import

Bug List (Steve)

Q&A

• Multiframe - same volume in multiple files?

• Database of Reference Datasets:
  • David Clunie has some samples (Mulitframe, SR, Segmentation...)
  • SlicerRT has many examples

• Other data types
  • DICOM Audio
  • Surfaces
  • Transforms
  • Statistics types?

• Attribute/Provenance handling
  • auto tracking
  • manual association
  • Use mrml hierarchies to encode patient/study/series

• Private tag decoder?
  • CSR in GDCM
