File Information
Description

Including diffusion tensor data calculation, fiber tractography and fiber tracts visualization Function.

[DiffusionTensorCalculation.m] will calculate the diffusion tensor, fractional anisotropy (FA), fiber direction eigenvalue and principle eigenvector.

[Tractography_STT_Euler.m] will will calculate fiber tracts by using Brute-force mathod, and tracking fiber by opposite directions.

[DtiSearch.m] is including ROI selection function and some fiber filter methods.

Required Products Image Processing Toolbox
MATLAB release MATLAB 7.10 (R2010a)

You can use MATLAB to write a program convert the images(ex: DICOMs etc.)to fit the format of my data. Or modify the data loading part of the code (DiffusionTensorCalculation.m).

First of all, thank you very much for sharing your code.

I have one questions:

-If I have a DICOM or a Nifti image,what do I have to do to use them in your program?

Thank you very much for everything in advance.

Great! Thanks.

Yes, The method of fiber tracking is based on the reference [Basser, P.J., et al., In vivo fiber tractography using DT-MRI data. Magn Reson Med, 2000. 44(4): p. 625-32.].

Is this implementaion based on a technique that was previously reported in literature? Your reply would be greatly appreciated.
