Hello Rich,
Is it possible that you're referring to an algorithm for correction of
gradient non-linearity in 3D T1w acquisitions? I've worked with two
Philips sites in setting up a multi-site FMRI protocol, and in neither
case did either site say that a Fieldmapping based correction of BOLD-
EPI data was automatically incorporated into the Philips BOLD-EPI
acquisitions.
cheers,

However the Phillips physicist informed me the Achieva uses its own undistort algorithm when the images are acquired. The take-home message was the fieldmap toolbox wouldn't be able to undistort anything. Not sure whether this helps you but I would be interested to hear if you made any progress at your scanner.
