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.
