Increased use of multichannel coils and phase sensitive analysis requires coil combination techniques beyond the traditional square root of sum of squares. For multiple echo acquisitions used in B0 and quantitative susceptibility mapping, pixel wise singular value decomposition can be used to generate phase sensitive optimum, in a least squares sense, coil sensitivity and image magnetization estimates.
