Abstract
A magnetic resonance excitation RF pulse (50) is applied to excite resonance in selected dipoles in an image region. A first phase encode gradient (56) phase encodes the resonating dipoles with one of a plurality of preselected phase angles. A magnetization rotation RF pulse (60), typically 90.degree., causes a primary echo (62) which is phase encoded with the preselected phase angle. A second magnetization rotation RF pulse (70) rotates the magnetization, typically 90.degree., to cause a stimulated echo (72). A second phase encode gradient pulse (78) is supplied subsequent to the second magnetization rotation pulse to alter the phase angle with which the stimulated echo is phase encoded. In this manner, data collected during the primary and stimulated echoes have different phase encoding such that more than one phase encoded view of data is generated following each excitation pulse.
