Dear BUCNI users
I'm operating the scanner for another group this morning and we're running a field map at the end of the session. I haven't used field maps before and so am unsure what I'm expected to do re planning. I've tried (on Oliver's advice) adjusting the protocol with copy parameters and 'adjust volume' from the previous EPI, but when I run it through I get the following warning:
'The adjust volume is normally calculated automatically. In this protocol it was changed explicitly. It is strongly recommended to readjust the adjust volume manually or to fall back to the automatic mode.'
When I choose Automatic, I get the yellow slice region box set in the middle of the field of view, not angled.
When I choose Manual, the planning view shows me a yellow box in the same position as above, and a green angled box showing the planning from the previous EPI sequences.
Can anyone explain what's going wrong here, and what I should be doing instead?
Thanks all,
Carolyn
