MRI can encode clinically important information in the image-phase, thus has great potentials to extend its capability for clinical applications. However, if phase references are not available, the multi-coil phase combination using the weighted average suffers from dominant signal losses coming from phase cancellations due to uncompensated coil-dependent phase offsets.
In this work, we developed a self-calibrating multi-coil phase combining method which does not require any additional scans for phase references. When applied to a single-point Dixon imaging, we verified the proposed method could successfully estimate the global phase-map with the minimal signal loss only using a single-scan image.
