摘要

System, method and computer-accessible medium can be provided to facilitate a hybrid adiabatic-rectangular pulse train for saturation of magnetization within an anatomical structure. -Using such exemplary embodiments, it is possible to determine information by combining a first information associated with a first nonselective rectangular radio frequency (RF) pulse, a second information associated with a second nonselective rectangular RF pulse, and a third information associated with a nonselective adiabatic half-passage pulse. Further, it is possible to rotate the longitudinal magnetization onto a particular plane (e.g., the transverse plane) based on the information. In addition, it is possible to minimize and/or achieve the residual longitudinal magnetization to be less than a predetermined threshold value (e.g., 2% of equilibrium magnetization) within the anatomical structure using a configuration of RF pulses.
