Abstract
A magnetic resonance imaging (MRI) system and method is provided. The MRI system comprises a plurality of transmit coils arranged spatially distinct from each other and configured for inducing a nuclear magnetic resonance (NMR) excitation. The NMR excitation is selective both in spatial dimensions and in a chemical shift spectrum. The plurality of transmit coils are driven by a plurality of radio frequency (RF) pulses, and a gradient module is driven by a plurality of gradient pulses.

A magnetic resonance imaging (MRI) system comprising:
- a plurality of radio frequency (RF) transmit coils and a gradient module, the plurality of RF transmit coils being arranged spatially distinct from each other and configured for inducing a nuclear magnetic resonance (NMR) excitation, the NMR excitation being selective in spatial dimensions and in a chemical-shift spectrum, wherein the plurality of transmit coils are driven by a plurality of radio frequency (RF) pulses concurrently with gradient pulses applied to the gradient module.
A method for magnetic resonance imaging (MRI), the method comprising:
- controlling respective currents in multiple transmit coils to induce a nuclear magnetic resonance (NMR) excitation over a selected spatial region of an object and a selected band of resonance frequencies.
