Dear All,
I've done realignment (estimate and reslice) on 246 EPIs (taken in one
continuous scan), and the result showed a total 7mm continuous movement
in the y direction (see attached 1st.fig), which led me doubt the
quality of images and/or realignment. I went ahead to do another
realignment based on the already realigned 246 scans and got the result
of very small movement in all directions (see attached 2nd.fig), which
made me believe the 1st realignment job was fine. However, I have never
got such big continuous translation in one direction. Is this set of
images reliable? Is there another way to check if anything is wrong
with my images?
Thanks,
Wei
