Magnetic Resonance Spectroscopy Water Suppression Method and Device

The SCSA method can be used pulse-shaped signals such as magnetic resonance spectra (MRS) signals. It is used for suppressing the water line in an acquired MRS signal y, the method including receiving the acquired MRS spectra y; estimating a water peak y_wp for the acquired MRS spectra y using squared eigenfunctions ( ɸ) of a Schrodinger operator H ; and removing the water peak y_wp from the acquired MRS y, to obtain a suppressed water MRS spectra y_ws. The suppressed water MRS spectra y_ws include a signature of one or more metabolites.
