Since traditional multicoil water-fat separation methods process data for each channel individually, they are computation intensive and have poor noise resistance performance. This work aims to investigate a new method which can combine multichannel phase images optimally before performing the complex-fitting based water-fat separation. Compared with the traditional method, our method can not only significantly shorten the calculation time but also improve the quantification accuracy and noise resistance. And this method is not limited by in- or out-phase echo times.
