20120194184 | METHOD AND SYSTEM FOR DESIGNING EXCITATION PULSES FOR MAGNETIC RESONANCE IMAGING - Methods and systems for designing excitation pulses for magnetic resonance imaging are provided. One method includes parameterizing spin-domain rotation parameters to define parameterized variables and defining a constrained optimization problem based on the parameterized variables. The method also includes solving the constrained optimization problem and generating parameters for the RF pulses based on the solved problem, wherein the RF pulses are one of multidimensional RF pulses on non-constant gradient trajectories or one dimensional RF pulses on non-constant gradient trajectories. | 08-02-2012 |
