The power of 2D selective RF pulses is to excite any spatial pattern within the field of view. However, the length of these pulses causes artifacts that especially affect background suppression. It can be observed that conventional 1D slice selective RF pulses have a superior sharpness and background suppression compared to 2D selective pulses. The goal of this study is to transfer these qualities of a 1D slice selective RF pulse to a 2D selective excitation
