Abstract
A method for performing MRI, including imposing N sets of steady-state free precession (SSFP) sequences on an object to be imaged, the sequences including respective initial radio-frequency (RF) excitation pulses, each initial RF excitation pulse having a predetermined phase shift relative to the other initial RF excitation pulses. N is a whole number larger than one and less than six. The method further includes setting the phase shift of the RF pulse of the sequences so that the phase shift of the RF pulse of an Mth sequence is substantially equal to radians, wherein M is a whole number larger than 0 and less than or equal to N, receiving a respective set of image signals from the object responsive to the N sets of SSFP sequences, and processing the set of received image signals to generate an image of the object.
