Abstract
Described here are systems and methods for magnetic resonance imaging ('MRI') using a sweeping frequency excitation applied during a time-varying magnetic field gradient. As an example, a gradient-modulated offset independent adiabaticity ('GOIA') approach can be used to modify the pattern of the sweeping frequency excitation. Data are acquired as time domain signals and processed to generate images. As an example, the time domain signals are processed using a correlation between a Fourier transform of the gradient-modulated sweeping frequency excitation and a Fourier transform of the time domain signals.
