Abstract
Selectively exciting bulk protons in certain tissue components, e.g. water, while suppressing the excitation of others, e.g. fat, can lead to images with better contrast for desired features. The invention provides binomial, off-resonance RF excitation pulses for differentiating tissue excitation that yields a larger fat suppression that prior art water excitation methods. Proper balancing of the frequency offset and the pulse duration with a relative phase offset between the pulses leads to large-bandwidth pass- and stopbands for water and fat, respectively. The pulses can be applied with short, or even zero, interpulse delay, leading to substantial time savings in the imaging sequence.
