Module Description
This module provides support for exploring multivolume (multiframe) data.
Use Cases
Most frequently used for these scenarios:
- visualization of DCE MRI
Tutorials
- Screencast tutorial (note that the module is located in Modules -> Work in progress -> MultiVolume Support, not in Modules -> MultiVolume Support, as shown in the video)
- Sample datasets are available:
- anonymized prostate DCE MRI DICOM series
- File:Cardiac ECGg CT.tgz (ECG-gated contrast-enhanced cardiac CT) (use "User-defined non-DICOM" parameter option to load it into MultiVolumeImporter). Short movie
Panels and their use

References
- 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)
Information for Developers

Section under construction. |
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
