摘要

A process for the correct of a magnetic resonance signal in the mr - spectroscopy,comprising the steps of:– Production of mr - data,– A model of a base line on the basis of the mr - data in a finite time range up to a predetermined -performing time point t_B, the significantly shorter than the time duration of the entire mr - data, in such a way that the modeling of the base line according to the -performing time point t_B drop to zero,– Subtracting the modeled base line in the time range of all of the mr - data to produce of in the time domain base lines - corrected mr - data, and– Transformation of the base lines - corrected mr - data in the frequency range.the step of modeling road height comprises the base line further comprises the steps of:– Estimating a metabolites model, in which at least one metabolites signal in the time domain, with the omission of the chronologically first mr - data,– Subtracting the estimated metabolites model of all measured mr - data and modeling of the base line on the basis of the subtraction result.
