RF phase encoded MRI uses spatial RF phase gradients in place of B0 gradients coils to encode information. Using a nonlinear RF phase gradient coil instead of linear one leads to a larger field of view. However, this coil will generate an in-homogeneous B1 field which result in pulse imperfection. To minimize the effect of pulse imperfection, the application of composite pulses is required. Current composite pulses were designed to use in current MRIs (having gradient coils and uniform RF coil), so the feasibility of working composite pulses with an RF encoded coil needs to be checked.
