The invention provides for a magnetic resonance imaging system (300, 400) for acquiring magnetic resonance data (342) from an imaging zone (308). The magnetic resonance imaging system comprises a processor (330) for controlling the magnetic resonance imaging system. Execution of instructions cause the processor to acquire (100, 200) the magnetic resonance data using a Dixon pulse sequence (340) to control the magnetic resonance imaging system; reconstruct (102, 202) a water image (346, 504, 1424) and a fat image (344, 506, 1422) from the acquired magnetic resonance data, wherein the water image comprises a first set of complex valued voxels, wherein the fat image comprises a second set of complex valued voxels; calculate (104, 204) a modified image (348, 902, 1440, 1502, 1602, 1700, 1702, 1704, 1706, 1708) comprising a first set of real valued voxels, wherein the set of real valued voxels is calculated as follows: for each voxel, its real value is calculated by taking the n-th root of the weighted sum of the modulus of the complex value at the corresponding voxel of the first set of complex valued voxels raised to the power n and modulus of the complex value at the corresponding voxel of the second set of complex valued voxels raised to the power n, with n>1. |
