Assertion

• Only the setup and testing of the system in last two sections have been successful can we start to perform the following fiducial seeding for DTI tractography.


Outline

• Load tensor image

• Create a fiducial list

• Configure Tractography module

• Configure NeuroNav module


Load Tensor Image

Go to Volumes module to load the tensor image


Create a Fiducial List

Move your mouse into any 2D slice window and then press “P” key while holing left mouse button. You will see a fiducial right way, which is named “L-P”


Configure Tractography Module

• Go to Fiducial Seeding by the following sequence:Modules -> Tractography -> Seeding -> Fiducial Seeding• In the tab of Tractography Seeding From Fiducial– Set “L” for Select FiducialList or Model– Set “Create New Fiber Bundle” for Output

Fiber Bundle Node


Configure Tractography Module

Set two values


Configure NeuroNav Module

Set the node name to BioImageSuite

Click this button to start seeding


Result

• At this point, you should see fiducial seeding of DTI tractography on fly. Check the tutorial for comparison.
