Abstract
A method for magnetic resonance imaging (MRI) using a radial cone k-space trajectory is provided. The radial cone k-space trajectory is defined by the application of a radial magnetic field gradient and one or more oscillating magnetic field gradients. The amplitude of the radial magnetic field gradient increases with time before decreasing with time. While the amplitude of the radial magnetic field gradient is decreasing, the one or more oscillating magnetic field gradients are applied. As a result, the radial cone k-space trajectory is one that is oriented along an axis and that extends outward from an origin along a substantially radial trajectory before extending outward from the origin while circumscribing a conical volume having a radius that increases nonlinearly with distance from the origin.
