A new comprehensive spiral gradient waveform correction strategy is proposed that features multipoint gradient anchoring (MGA). By measuring multiple gradient delays in spiral waveforms at different rotation angles, it effectively ‘anchors’ the waveform at a series of locations and improves gradient waveform fidelity. Application of this innovative design on phantom and volunteer imaging indicates it is an effective and promising technique.
