DTI echo-planar distortion correction

Postby m.roth » Mon Jun 29, 2009 12:27 pm

Hi everybody,

I work in Marseille on a Bruker 3T MRI system. I acquired DTI images with 16 T2 images and 48 b1000 directions. I import these data in my BrainVISA database. Then I try to run DTI echo-planar distortion correction. After few seconds, a pop up window show a memory problem and the following error message appear in the brainVISA window :

Do you have an idea of what is the problem and how I can resolve it ? Thenk you for any help,

Hi Muriel,

Could you send us your data so that we see if we have the same error ?
