Dear MRICRO-Users,
I am trying to perform a subtraction analysis between 2 patient groups and I
have the following problem: Since in some patients we don’t have any digital
images of the patient MRI-scans, we draw the ROIs (strokes) by hand onto the
template brain of the MRICRO. However, we cannot make overlap images or
subtract the ROIs of the patient groups, because the slices we used to draw
the ROIs and their rotation are not identical in every subject (in order to
fit the orientation of the actual MRI-slice).
1.Is there a way to “interpolate” ROIs on slices that are between those that
have the ROI mapped?
2.And how can we solve the problem of the variability in rotation
coordinates across patients?
Thanks for any suggestions,
