A Phase-Offsets Estimation from Multi-echoes (POEM) method is proposed to combined the phase-arrayed coil at 7T for quantitative susceptibility mapping (QSM). The method demonstrates equivalent or better results than adding a conventional reference scan for both single-orientation and multi-orientation QSM.
