Hi all,
I have sets (different subjects) of MR stacks aquired
with 2 different sequences one is an EPI and the other
is an anatomical scan. For analysis I prefer to avoid
co-registration for most of the cases and do
registration only for those cases that would "really"
need to be co-registered. Given the distortions
associated with EPI I would like to know how should I
decide if registration is necessary? Other than just
visually inspecting the stacks I would like to know if
there is any quantitative method for this matter? let
me mention that I'm going to do some ROI based
analysis on these data.
I would also like to ask another question: say you
have coregisterd two images how will you evaluate "the
goodness" of registration?
Best,
Nas
