Latest Patents

Derbyshire holds a patent titled "Method for spectrally selective B1 insensitive T2 preparation contrast enhancement for high field magnetic resonance imaging." This patent describes a T-preparation sequence that utilizes a segmented BIR-4 adiabatic pulse with two substantially equal delays. The method is designed to be insensitive to B-field variations while simultaneously suppressing fat signals with a low specific absorption rate (SAR). The process involves applying an adiabatic reverse half passage pulse followed by a predetermined delay, an adiabatic full passage pulse, and then an adiabatic half passage pulse. Fat signal suppression is achieved by adjusting either the first or second delay.
