I have a feeling this has been asked countless times before
I have an oblique dataset
my gradient directions are relative to the magnet.
I want to rotate my gradients to be relative to my image.
I have a feeling that it should be just multiplying some rotation matrix by the gradients, but i've tried IJK_DICOM_TO_REAL and the resultant directoins are no longer normalized. Plus, i'm uncertain that the rotation in this matrix is about the origin.
Thoughts?
Thanks
Drew
