Abstract:
1. A method of processing magnetic resonance imaging signals from a plurality of magnetic resonance imaging coils, comprising: receiving a plurality of signals, s creating a subset of the plurality of signals, s determining a noise covariance matrix, N, of the subset of the plurality of magnetic resonance imaging coils, wherein the noise covariance matrix, N, of the subset of the plurality of magnetic resonance imaging coils is a Hermitian symmetric matrix; converting signal vector S to signal vector Ŝ, where, Ŝ=(K*) calculating a composite pixel value for the location, √{square root over (Ŝ*·Ŝ)}, where Ŝ*=[(K*) producing a pixel for the location in an image, wherein the pixel for the location in the image has the calculated composite pixel for the location.
