Abstract
A magnetic resonance imaging (MRI) process generates images of patient tissue including use of at least one programmed controller in an MRI system to effect a preparatory nuclear magnetic resonance (NMR) sequence including a binomial radio frequency (RF) pulse having at least two independently phased RF flip angle components that are spaced in the time domain by τ to provide a respectively corresponding evolved phase difference Δθ between predetermined NMR species having different NMR frequencies, followed by a main MRI data acquisition sequence, and generation and display of an image of patient tissue based at least in part on MRI data acquired during the acquisition sequence.
