Agenda breakout session: Multi-Image Engineering in slicer
Wednesday 8-10am
Session Leaders: Jim Miller, Steve Pieper, Alex Yarmakovich, Junichi Tokuda, Demian Wasserman
Contents
Background
Increasingly, we have data in slicer which are multi something. Examples are:
- multi-channel (T1, T2, flair, dual echo, etc.)
- DWI
- rgb and other multi-channel images
- time series
Current State
We have part of the ability to handle such multi-dimensional volume in the DWI infrastructure:
- Dicom to nrrd, the slider in the volumes module to look at any of the individual volumes in DWI.
- Junichi's TimeSeriesBundleNode is a mrml node to organize 4D data.
- Brainsfit has the ability to register such multi data sets to each other and Gtract has a first solution which is engineered for DWI
- Compareview would allow to show multi data in compareviewers. When we have a few volumes, then we can display all. If its a large number of volumes, we will only be able to display a few. Some engineering work will be needed to make this easy on the user.
Existing Processing capabilities
Multi volumes are processed in Slicer in specialized ways.
- Parametric analysis:
- DTI estimation from DWI
- Tofts parameter estimation from DCE
- Segmentation:
- EM segmentation from multi-channel morphology data
The Need
All of the current examples are special cases. If we can generalize those into a single architecture for multi data, there would be a lot of potential for cross-benefits.
I/O
- We should have a single module to organize the data. DICOM to nrrd is a good start, but we need to be able to handle separate T1 and T2 acquisitions as well. We also need to be able to handle non-dicom data. Perhaps something like: load all data into slicer and associate them inside slicer in a special module. Write out as a single nrrd file.
Display
- we should create a single visualization infrastructure to handle multi data: compare viewers, rgb channels, time series movies: equivalent slice viewers and 3D viewers
Processing
- common api for processing: EM segmentation, pharmacokinetic models, DWI filtering, tensor estimation should all plug into the data in the same way.
