| titleOfInvention | Magnetic resonance depth measurement method for extracting signal based on frequency selection singular spectrum analysis |
| abstract | The present invention is a kind of magnetic resonance depth measurement method for extracting signal of singular spectrum analysis based on frequency selection.MRS signal regional known to water instrument acquisition Larmor frequency, which is visited, first with nuclear magnetic resonance depth measurement finds the position of the corresponding MRS signal of Larmor frequency on power spectrum based on power spectrumanalysis after carrying out partial noise inhibition by broadband bandpass filter；Then, the singular spectrum analysis selected based on frequency is carried out to extract MRS signal.Singular spectrum analysis based on frequency selection includes being embedded in, RSVD decomposition, carrying out matrix reconstruction according to the corresponding singular value of MRS signal amplitude selection and diagonally equalize four steps.The present invention is able to solve effectively filtering out for random noise in noisy MRS signal, spike noise and industrial frequency harmonic interference, realize that complicated very noisy interferes effective extraction of lower MRS signal, compared with traditional MRS signal antinoise method, have many advantages, such as that arithmetic speed is fast, signal-to-noise ratio is high, practical. |
