Method and system to enhance medical signals for real-time analysis and high-resolution display

摘要

A medical processing and display system that may be used with a medical monitoring device. This system enhances the medical data it receives. Once received, the medical data is reformatted into a two- dimensional matrix, X. A history database and other information are concatenated with the two-dimensional matrix. The concatenated matrix is decomposed using singular value decomposition ("SVD") to obtain corresponding left and right singular vectors, L and R, respectively, and singular values D. Selected singular vectors are transformed to their autocorrelation matrix form, which are concatenated, then decomposed using SVD to their corresponding singular vectors P, P.sup.t, and singular values D. Certain of the singular vectors P are selected to filter out signal components of interest. The singular values D of the autocorrelation matrix are modified and used to adjust the weights of the associated singular vectors P. The weighted singular vectors are then combined and the resulting coefficients are used as a FIR filter to enhance the original singular vectors L and/or R.sup.t to enhance singular values L.sub.e, R.sub.e. Enhanced medical data containing the features of interest X.sub.e is generated from the enhanced original matrix singular values L.sub.e and R.sub.e, and modified singular values D.sub.e, and the results may be displayed to a diagnotician in various formats.
