Zusammenfassung:A device (18) configured to filter magnetic resonance (MR) signals includes, at least one electronic processor (24) programmed to: receive at least one MR signal (26) excited in a subject disposed in an MR imaging device (10); transform the at least one MR signal with a coherence function representing the at least one MR signal as an instantaneous frequency spectrum as a function of time; apply spectral filtering to the transformed at least one MR signal; and reconstruct at least one medical image from the filtered at least one MR signal.
