Module Description

Allows the user to modify the display of diffusion tractography. Examples are: change of color, display of the fractional anisotropy along the tract, display of the tracts as tubes or lines, interactive selection of the tracts, and cropping.

Use Cases

Most frequently used for these scenarios:

• Use Case 1: Change the scalar quantity displayed along the tract, like Fractional Anisotropy or Color By Orientation
• Use Case 2: Display the tracts as lines or tubes
• Use Case 3: Interactive selection or cropping of a certain bundle.

Panels and their use

Line: Display the tracts as lines Tube: Display the tracts as tubes Slice Intersection: Show the tracts in the 2D view Glyph: Display glyphs representing the diffusion tensors along the tracts Percentage of Fibers Shown: Select how many of the total tracts in the bundle are shown. Useful for performance. Fiber Bundle Selection: Perform interactive selection and cropping of the tracts ROI for Fiber Selection: Select a ROI to use as an interactor with the tracts Disable/Positive/Negative ROI: Set the selection mode to Select everything; Select the tracts traversing the ROI; Select the tracts not traversing the ROI Create Bundle From ROI: Create a new fiber bundle which contains only the selected ones Update Bundle From ROI: Update the current fiber bundle leaving only the selected ones Advanced Display: For the lines, tubes and glyphs Visibility: Toggle the visibility of the bundle Opacity: Change the transparency level of the bundle Color By: Change the way the bundle is colored; either by a tensor-derived property or by a group id Solid Color: Color the bundle of a single solid color Similar Modules Models References http://slicerdmri.github.io/ Information for Developers https://github.com/SlicerDMRI
