Abstract
Described here are systems and methods for volumetric excitation in magnetic resonance imaging ('MRI') using frequency modulated radio frequency ('RF') pulses. In general, quadratic phase modulation along the slice encoding direction is implemented for additional spatiotemporal encoding, which better distributes signal content in the slice direction and enables higher acceleration rates that are robust to slice-undersampling.
