|4868501||Method and means for magnetic resonance spin-echo imaging using an adiabatic three pi pulse sequence|
An adiabatic pulse suitable for generating selective spin echoes for both MR imaging and spectroscopy is described. The pulse requires no gradient reversal to achieve phase compensation. Like adiabatic inversion pulses the new pulse performs a π rotation...
|4760336||Variable rate magnetic resonance selective excitation for reducing rf power and specific absorption rate|
In magnetic resonance imaging where a subject is placed in a static field and the subject is selectively excited by applying an RF magnetic field in the presence of a gradient magnetic field, the peak RF power of the RF magnetic field is reduced by decrea...
