Purpose
Either SENSE+CG or POCS‐ICE methods can be used to correct for motion‐induced phase errors in navigator‐free multishot diffusion imaging. SENSE+CG has the advantage of a fast convergence, however, occasionally the convergence can be unstable, thus degrading the image quality. POCS‐ICE has a stable convergence and can be used with a high number of shots, but its convergence is slow, which...
Purpose
For multishot diffusion weighted imaging (DWI), one of the challenges is to remove phase variations induced by physiological motion among different shots. In this study, a new method is proposed to iteratively solve the phase errors and DWI images simultaneously, for navigator‐free acquisitions.
Theory and Methods
Instead of solving phase errors and the image sequentially in the two‐step...
