Abstract
A system and method for acquiring image data from an object that includes a plurality of spins is described. A magnetic field is applied to the object to align the spins along a longitudinal axis. A first pulse is applied to the spins for rotating the spins from the longitudinal axis toward a transverse plane. Image data is acquired from the spins during a free precession interval in which the spins precess in the transverse plane. A second pulse is applied to the spins for rotating the spins from the transverse plane to at least substantially along the longitudinal axis. At least one of the first and second pulses is spectrally or spectrally-spatially designed.
