Abstract
Adiabatic pulses that define an amplitude modulation and a frequency modulation are applied in a sequence of pulses to obtain a Tweighted magnetic resonance image. Such an adiabatic Tprep sequence typically includes a first 90° pulse, an even number of adiabatic pulses, and a second 90° pulse. Adiabatic pulses can be selected based on function pairs, or can be defined numerically. A magnetic resonance imaging (MRI) system includes a library of adiabatic pulse waveforms, and is configured to select a waveform and apply an RF magnetic field based on the selected pulse waveform.
