Highlight text to annotate itX
The open button is located to the top left.
Left mouse: Rotation
Right mouse: Navigation
Each item in the list has its own Properties panel.
Let's open a new item.
Use the arrows to change the display order.
Since we have atleast 1 anatomy in our scene, we can now load 3D objects.
For example, a white matter mesh.
As expected, it has is own Properties panel
Other maps can be visualized (ex: RGB)
As always, let's open an anatomy first.
And then the fiber tracts
Fibers have their own properties too.
Let's add a selection box
This acts as a VOI
The VOI list has their own Properties panel too.
The box size can be adjusted by holding Ctrl+Right click on each axis
VOIs can also interact between them.
The logical operations available are AND, OR, ANDNOT.
Fiber stats can be displayed for a certain VOI.
The box size can also be adjusted manually.
This is a basic ODFs field showing crossing regions.
Be aware of the different basis available, depending on your data.
Their maximas can be extracted.
The scale slider can be adjusted.
This module permits the user to tune a series of parameters involved in the tracking process.
Lets open a tensor field.
They can be displayed as sticks also.
Back to the realtime module, specify the tensors file.
Using a selection box, the user can start the tracking process.
Fibers are calculated in realtime while dragging the VOI. (Note that the video recording affects the fluidity)
Every change to the parameters will be reflected on the fiber tracts instantly.
Let's perform whole brain fiber tracking.
By generating an isosurface from the FA map, we rouglhy cover the gray matter/white matter interface.
Select the newly created surface to seed from. (Note that it could be anything, such as a solid tumor).
Enable the Shell seeding option, and start back the tracking process.
Let the fibers compute.
Hit the "Convert Fibers" button to create a new 3D object into the list.
By hiding the isosurface, and stopping the tracking process, one can explore the newly generated fibers with the use of VOI.
Turning off the VOI will display all the fibers.
