Patent number: 12072402Abstract: Systems and methods are provided for multiphotonic magnetic resonance imaging. The system uses one or more (B1,z) RF coils or oscillating gradients oriented along the z-axis to provide multiphoton resonances. The B1,z coils can be implemented as planar coils or solenoids. With the additional coils, standard slice-selective pulse sequences have all standard excitations replaced with multiphoton excitations that excite extra resonances. In vivo imaging using multiphoton excitation has signal to noise ratios comparable to single-photon excitations when similar pulse sequences are used. Since excitation is not bound to the Larmor frequency, new RF pulse sequences can be designed with imaging methods patterned after single-photon excitation concepts.Type: GrantFiled: May 24, 2022Date of Patent: August 27, 2024Assignee: THE REGENTS OF THE UNIVERSITY OF CALIFORNIAInventors: Chunlei Liu, Victor Han
