Abstract The goal of this work was to design improved Chemical Exchange Saturation Transfer MRI RF pulses applicable to whole-body clinical scanners. Conventionally, CEST imaging requires a long continuous wave saturation pulse, however, due to hardware limitations, only pulsed saturation is practicable for in vivo scanners. Consequently, RF pulses with a duty cycle of 90% are designed by optimal control. The simulation results were compared to a 100% duty cycle Continuous-Wave pulse and a 90% Gaussian standard pulse. The optimal control pulse showed superior efficiency to the Gaussian pulse and comparable performance to the Continuous-Wave pulse, while transmitting less energy to the patient.
