Abstract:
1. A method to detect interference signals in a magnetic resonance spectroscopy signal, comprising: providing a processor with at least one magnetic resonance spectroscopy signal, which contains interference signals and, in said processor, reconstructing a comparison signal from said magnetic resonance spectroscopy signal that approximates said magnetic resonance spectroscopy signal by recreating spectral components of resonance lines in said magnetic resonance spectroscopy signal and that does not include spectral components of said interference signals; in said processor, calculating a residual of a difference between said magnetic resonance spectroscopy signal and said comparison signal in frequency representation(b), said residual containing signal spikes in a degree correlated with said interference signals; from said processor emitting an electrical signal that represents the frequency representation of said residual; and from said signal spikes in said residual represented in said electronic signal, determining said interference signals.
