Adiabatic T2 Preparation Sequence for Magnetic Resonance Imaging with Reduced B1 Sensitivity (U.S. Patent Number US 7788930 B2)Adiabatic pulses that define an amplitude modulation and a frequency modulation are applied in a sequence of pulses to obtain a T2 weighted magnetic resonance image. Such an adiabatic T2 prep sequence typically includes a first 90° pulse, an even…
Method for Spectrally Selective B1 Insensitive T2 Preparation Contrast Enhancement for High Field Magnetic Resonance ImagingA T2 preparation sequence uses a segmented BIR-4 adiabatic pulse with two substantially equal delays and is insensitive to B1 field variations and can simultaneously suppress fat signals with low specific absorption rate (SAR). An adiabatic reverse…
