[Mristudio-users] Fibre Tracking

[Benjamin Aribisala]

Dear All,

I am new to dtistudio, so please permit my ignorance. I am trying to  
do fibre tracking, basically connecting two ROIs.

My DTI data were acquired on GE scanner and they have been converted  
to hdr./img format, motion corrected and eddy current corrected.  
Basically ready for the real processing. There are 7 bo images and 64  
directions, a total of 71 3D volumes, bo images were the first 7  
volumes. I could not find any online material that could guide me on  
how to use hdr/img images on dti studio. After playing with dtistudio,  
I found that the Philips REC option lets me read in hdr/img and do dti  
mapping. I then attempted to do fibre tracking, but got nonsensical  
tracts, connecting everywhere to everywhere.

I will be very happy if anyone could please help or suggests which  
online materials I could read, I have watched the video mristudio  
website, but it does not seem to help.

Thanks for your anticipated lifesaving help
