提出了一种新的算法，该算法利用两点狄克逊（2 PD）方法的同相和反相采集来提供单独的水、脂肪和B-O图像。扩展方法（E2 PD）的准确性与三点狄克逊（3 PD）方法相比毫不逊色，并且采集需要2/3的3 PD扫描时间。与3 PD方法相比，由于B-o场图中的SNR降低，在含有水和脂肪混合物的像素中可能会出现略微增加的误映射。
A new algorithm is presented that provides separate water, fat, and B-o images utilizing the in-phase and opposed-phase acquisitions of the two-point Dixon (2PD) method. The accuracy of the extended method (E2PD) compares favorably with the three-point Dixon (3PD) method, and the acquisition requires 2/3 the 3PD scan time. Slightly increased mismapping may occur in pixels containing an admixture of water and fat due to reduced SNR in the B-o field map compared with the 3PD method.
