Magnetisation rewind during a finite RF pulse in gradient echo magnetic resonance imaging
Abstract
Profile degradation due to a finite radio frequency pulse width in broadline (solid state) gradient echo magnetic resonance imaging can be considerable. A method for overcoming the problem by shifting the timing of the pulse relative to the gradients or by rotating the profile by a spatially dependent angle is described and demonstrated.
