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

Adiabatic RF pulses play an important role in spin inversion due to their robust behavior in the presence of inhomogeneous RF fields. These pulses are characterized by the trajectory swept by the tip of the Beff vector and the rate of motion along it. In this paper, we describe a method by which opt
## 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. βMinimum distanceβ was the main formulation used for the s
