Latest Patents

Shimon L Panfil holds a patent for "Fast adiabatic pulses." This patent discloses new methods of generating optimal inversion pulses and adiabatic pulses in magnetic resonance imaging. The invention utilizes trajectories, maximum sweep rates, and velocity profiles to define an optimal pulse over support regions. Adiabatic pulses are optimized by using the trajectory as a constraint of optimization, selecting trajectories with velocity profiles, and not relying on the adiabatic condition as a constraint for optimizing the velocity profile. The patent also describes a method for inverting MR spins substantially, independently of the pulse duration, by selecting a transition width between 1.4 and 1.9 and dividing that width by the pulse duration. Additionally, it introduces a new method of inverting adiabatic, MR, amplitude-modulated spins, with a trajectory defined by sin(α)/cos(α), where α < 0.9, and at least 50% of the trajectory is outside in a z-x rotating frame of reference that rotates at the instantaneous frequency of the RF pulse.
