Abstract
A magnetic resonance imaging system (78) includes a magnetic resonance imaging device (80), one or more processors (104), and a display (106). The magnetic resonance imaging device (80) includes a magnet (82), gradient coils (88), and one or more radio frequency coils (92). The magnet (82) generates a Bo field. The gradient coils (88) apply gradient fields to the Bo field. The one or more radio frequency coils (92) generate a radio frequency pulse to excite magnetic resonance and measure generated gradient echoes. The one or more processors (104) are configured to activate (116) the one or more radio frequency coils (92) to generate a series of radio frequency pulses spaced by repetition times and to induce magnetic resonance. The one or more processors (104) are configured to control (118) the gradient coils to apply after each RF pulse readout gradient field pulses which refocus the resonance into a plurality of gradient echoes, shift and refocus gradient field pulses which shift and refocus at least one of the echoes to a subsequent repetition time, and receive and demodulate the gradient echoes to form k-space data lines. The one or more processors are configured to reconstruct…
