Module Description

This module provides support for exploring multivolume (multiframe) data.

Use Cases

Most frequently used for these scenarios:

  • visualization of DCE MRI
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.

Information for Developers


Known issues that won't be resolved

  • bug 1841: multivolumes that contain less than 7 frames will not be saved correctly and the scene containing such objects will not be loaded correctly by Slicer (limitation of the NRRD IO for DWI)

Unresolved issues

  • assign correctly title and points for the X axis
  • review the comments from JC/J2 on github and fix the code
  • bug: repeated loading of a scene that contains a MV node causes crash in onInputChanged()
  • improve error reporting!
  • look into flickering issue of vtkChart
  • improve documentation

Features to be implemented

  • integrate MV importer as a DICOM module plugin
  • allow the user to speed-up or slow-down the playback, and also turn off "loop"
  • report to the user the actual, measured, frame rate
  • add an option to report curves in relative SI change in addition to absolute

Features under consideration

  • 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)
  • 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?
  • add GUI elements to update the current frame at the exact time intervals specified in multivolume. If the intervals are non-uniform, I am not sure I can use the timer anymore, so this would require some extra thought.
  • import multivolumes from ITK 4d images
