Screenshot of charts derived from the sample data set. The curves represent average signal intensity in the ROI's with corresponding colors, which were drawn in the editor. Please note the arterial input function in red.

This is a placeholder for MultiVolumeExplorer module documentation.

Development of this module was initiated at the 2012 NA-MIC Project week at SLC (see http://wiki.na-mic.org/Wiki/index.php/2012_Project_Week:4DImageSlicer4)

The module is located in Modules -> Work in progress -> MultiVolume Support

Disclaimer: this module is Work in progress. This means that

• the functionality provided by this module may change drastically in the future releases of 3D Slicer
• the scenes containing data types specific to this module may not be readable by the future versions of Slicer
• the functionality and user interface may change at any time
• some functionality may not work as intended
• testing and documentation is limited

If you would like to try this module:

1. download the sample dataset [1] (anonymized prostate DCE MRI DICOM series)
2. check out this screencast if you would like to learn how to use this module. (The module is located in Modules -> Work in progress -> MultiVolume Support, not in Modules -> MultiVolume Support, as shown in the video)

Unresolved issues:

• • look into memory management from python
  • add testing
  • look into flickering issue of vtkChart
  • assign correctly title and points for the X axis
  • review the comments from JC/J2 on github and fix the code
  • improve documentation

Resolved issues:

• • widget should be reorganized and improved for explorer module -- DONE
  • BUG: need to be in quantitative layout on startup, otherwise charting does not work -- FIXED
  • BUG: frames were not sorted on load, sometimes causing incorrect initialization of the multivolume -- FIXED
  • assign more intuitive names to the extracted frames -- DONE
  • look why DWI appears on the list of scalar volumes -- FIXED
  • look into why the chart view node is not recognized if the quantitative layout is not used initially -- FIXED
  • can we use chart viewer for interactive plotting? -- Discussed with Jim, speedup is possible, but not a priority right now
  • should use color names for the legend in the chart viewer -- Will be available as general feature of Charts (Jim)

Features under consideration:

• interactive update of the active frame based on the point selected in the chart viewer
• should DWI node be a child under the MV hierarchy?
