Adiabatic RF pulses play an important role in spin inversion where G is the adiabatic parameter due to their robust behavior in presence of inhomogeneous RF fields. These pulses are characterized by the trajectory swept by the tip of the B eff vector and the rate of motion upon it. In this paper, a
## Abstract Optimal control theory has been applied in the past for the design of RF pulses for selective excitation. This was the outcome of having established the controllability of the MR spin system for the selective excitation problem. “Minimum distance” was the main formulation used for the s
