Systems and Methods For Real Time Gradient Timing Modification

A magnetic resonance (MR) imaging system for modifying gradient timing, comprising:

• a radio frequency (RF) signal generator configured to generate RF excitation pulses in patient anatomy and enabling subsequent acquisition of associated RF echo data;
• a magnetic field gradient generator comprising a plurality of gradient coils configured to generate a sequence of gradient waveforms on a static magnetic field in three directions each orthogonal to each other for slice selection, phase encoding and readout RF data acquisition in the volume of patient anatomy;
• a controller configured to:
• (i) receive an indication of the sequence of gradient waveforms to be applied to a plurality of gradient coils;
• and (ii) modify the sequence of gradient waveforms based on one or more parameters to produce a sequence of modified gradient waveforms;
• and
• a plurality of gradient coils configured to acquire the sequence of modified gradient waveforms provided by the controller.
