Patent ID: 7057387

Claim:
A method of processing magnetic resonance imaging signals from a plurality of magnetic resonance imaging coils, comprising: determining a noise covariance matrix, N, of a plurality of magnetic resonance imaging coils, wherein the noise covariance matrix, N, of the plurality of magnetic resonance imaging coils is a Hermitian symmetric matrix; receiving a corresponding plurality of signals, s 1 ,s 2 , . . . ,s n , from the plurality of coils to produce signal vector S=[s 1 ,s 2 , . . . ,s n ], wherein the plurality of signals represent a corresponding plurality of pixel values for a location; converting signal vector S to signal vector Ŝ, where, Ŝ=(K * )·S and N=K * K, where K is a matrix for which the conjugate row-column transpose of K(ie K * ), multiplied by the matrix K is the noise covariance matrix, N; and calculating a composite pixel value for the location, √Ŝ • ·Ŝ, where Ŝ 500 =[(K * ) −1 ·S] * .
