[Insight-users] diffusionTensor3D, DTITubeSpatialObject and Tractography

[alba garin]

Hi all,
first of all thanks for your answer. i ve already seen 3D slicer but i am trying to build my own code with itk, vtk and qt classes so i did not use any of the modules. Besides, sometimes it is difficult to take any ideas from a big amount of source code. anyway, i am gonna try to take ideas from it.
any other ideas?
thanks,Alba

Hi Alba,
I noticed you have a couple posts recently about DTI with ITK. In case you don't know about it, I wanted to mention that 3D Slicer has DTI capabilities built-in, including conversion of DWI DICOM files to nrrd, fitting tensors, and visualization/selection. 



See here for more info:

http://www.slicer.org/slicerWiki/index.php/Documentation-3.6#Diffusion_MRI

Right now ITK is not used for the actual tensor work in the primary GUI modules; most of that is handled through VTK wrappings of Gordon Kindlmann's Teem library (on sourceforge). But Slicer has GTRACT tools wrapped too - which use ITK for everything. We are looking at ways to use more ITK because it has support for threaded filters (for faster estimation).



We are in the process of revamping the DWI-related GUI interface and extending (ie DSI, HARDI) support for the next major release. Slicer is BSD-licensed open-source (like ITK) and the mailing lists are always very welcoming to new users!



Cheers,
-Isaiah

good afternoon,
i am already using DiffusionTensor3D for representing every voxel in a diffusion tensor image. i ve already visualized the slice views of the brain in colors, representing the diffusion of the water (with a rgb itk image). Now i am trying to visualize the tracts, and i found the DTITubeSpatialObject. But i realized that it is similar to DiffusionTensor3D. 

1 .- are they similar or once i use diffusionTensor3D i do not need DTITubeSpatialObject? i think i need it coz in the object i have the tensor, the fa and the color (and more information) all together. 2.- what class of itk do you recommend me to represent the tracts? 


thanks,Alba
