The elliptical model method for removing residual banding in balanced steady state free precession images requires accurate phase information to operate. Most datasets have separate data for each coil channel with different sensitivity, requiring combination either before or after processing using the elliptical model to eliminate differences in coil sensitivity. We demonstrate that the order in which these steps are taken matters, requiring coil combination after processing with the elliptical model depending on the method.
