System and method for multiphoton parallel transmit excitation for mri

Abstract

A method for generating a magnetic resonance image of a subject using a magnetic resonance imaging (MRI) system includes receiving, using the MRI system, at least one parameter for a multiphoton parallel transmit excitation comprising a multiphoton excitation pulse configured to correct spatial inhomogeneities and performing, using the MRI system, a pulse sequence comprising the multiphoton parallel transmit excitation to acquire data from the subject. The multi photon excitation pulse of the multi photon parallel transmit excitation is performed using a radio frequency (RF) coil and a set of one or more shim coils of the MRI system. The method further includes generating, using a processor, an image of the subject using the acquired MR data. In some embodiments, the multiphoton excitation pulse includes an off-resonance RF excitation pulse performed using the RF coil and a plurality of low-frequency excitation pulses performed using the set of one or more shim coils. The plurality of low-frequency excitation pulses are performed simultaneously with the off-resonance RF excitation pulse.
