2D pulse sequences like 2D JPRESS suffer from long acquisition times and can benefit from the acquisition acceleration provided by phase array coils. Prior time-domain signal combination techniques have focused on aligning the initial phase of the multichannel FID to an arbitrary reference. The first time point samples are prone to phase errors. The current work shows that eddy current correction in a maximum echo-sampled 2D JPRESS sequence, using the unsuppressed water signal, implicitly compensates the phase offsets in a phased array coil. This can be used for coherently combining the phased array signals in the time domain.
