Hi,
quick question: Am I right that for Partial Fourier Sampling and Parallel Imaging I need to calculate my effective Echo Spacing (esp) according to:
effective esp = esp*(Partial Fourier Ratio, e.g. 6/8) / PAT-factor (e.g. 2)
?
To me it looks like accounting for Partial Fourier slightly under-unwarps the distortions whereas not accounting for it messes up the intensities in the undistorted EPI a bit.
Thanks + cheers,
Andreas
