Abstract
Methods and systems for production of silent, multi-gradient echo, magnetic resonance images includes employing iterative application of small updates to the magnetic field gradient followed by a short, non-selective radiofrequency pulse excitation and for free indication decay data acquisition. The magnetic field gradient updates allow for silent, self-refocusing pulse sequence. Each magnetic field gradient is based in part on a k-space spoke. The multiple spokes, when concatenated, produce a closed k-space trajectory, which results in the self-refocusing pulse sequence. The k-space spokes of the sequence of k-space spokes that forms the closed k-space trajectory oscillate in and out of a plane of a frequency space. Subsequent applications of the magnetic field gradients allow for multiple echo data acquisitions.
