Abstract
In a method for evaluating a time signal that is generated as a magnetic resonance signal by means of magnetic resonance technology and that contains spectroscopic information, an apodized time signal is formed by multiplying the time signal by a bell-shaped window function, an apodized spectrum is formed by Fourier transformation of the apodized time signal, an apodized informational spectrum is generated by removing noise components from the apodized spectrum, an apodized informational time signal is formed by Fourier back-transformation of the apodized informational spectrum, and an informational time signal is formed by multiplying the apodized informational time signal by an inverse function that corresponds in at least one section to the inverse window function.
