Stochastic Tracking View

Input Data

Mandatory Input:

• One DWI Image image selected in the datamanager
• One or more ROIs selected in the datamanager

For a successful execution of the stochastic tractography filter, a DWI input and a binary image defining the desired ROI are required. The ROI serves as the origin from where on the fibers are beeing tracked. To generate the seed ROI the segmentation view in the quantification perspective can be used or a binary image can be loaded.

Input Parameters

• Parameters such as max. tract length, number of seeds per voxel and likelihood cache size in MB can be controlled individually.
• After successfully setting necessary Input and Parameter, pressing the command button executes the algorithm.
