Abstract
Notably for MR spectroscopy it is important than an MR receiver for resonance signals has a large dynamic range in order to enable the reproduction of comparatively strong as well as comparatively to the weak signals in a spectrum. Therefore, the MR receiver should be linear to a high degree. Otherwise, for example in proton spectra metabolites are liable to be masked by peaks in tne spectrum which are caused by harmonic distortion and notably intermodulation distortion. An MR method is proposed for increasing the dynamic range of the MR receiver by software compensation of non-linearities in the MR receiver by means of a counter-distortion function.
