Single-shot EPI is a fast technique allowing the acquisition of an image following a single RF excitation. However, EPI is prone to geometric distortions in presence of magnetic field inhomogeneities. We propose here a new method based on the modelling of the PSF data signal to allow accelerated acquisition for accurate geometric distortion corrections.
