Developer Meetings/20141202

To discuss

• vtkMRMLDoubleArrayNode
• Update DICOM Scalar plugin to account for rotation
• CLIs that return coloured models

Conclusion

• Kevin will work with Csaba to improve the DICOM ScalarVolume plugin
• Nicole clarified the process to get colour information back from a CLI and into Slicer for Rohinee

vtkMRMLDoubleArrayNode improvements

• Ideas:
  • From Andras: vtkTableClass could be used.
    • http://www.vtk.org/doc/nightly/html/classvtkTable.html#details
  • Could create a vtkMRMLTableNode
  • From Nicole: There is also a vtkColorTableStorageNode
  • From Mike: It used to be hard to get to vtkVariants using python. Good news, now vtkVariant are wrapped. See http://vtk.org/gitweb?p=VTK.git;a=blob;f=Wrapping/Python/README_WRAP.txt#l373
  • Being able to import excel table / CSV data is really nice.

• Short/Medium term plan:
  • (1) Add a vtkMRMLTableNode and vtkMRMLTableStorageNode
  • (2) CLI integration: logic would have to be extended to transfer table
  • (3) Add qSlicerIO to save/load CSV files
    • voDelimitedTextImportWidget: https://github.com/Visomics/Visomics/blob/master/Application/voDelimitedTextImportWidget.h
    • voDelimitedTextImportSettings: https://github.com/Visomics/Visomics/blob/master/Base/voDelimitedTextImportSettings.h
    • voDelimitedTextPreview: https://github.com/Visomics/Visomics/blob/master/Application/voDelimitedTextPreview.h
  • (4) Add table visualizer
    • vtkExtendedTable: https://github.com/Visomics/Visomics/blob/master/Base/vtkExtendedTable.h

• Long term plan:
  • Concept of MRML table node could be extented to connect to a database
