Automated determination of the resonance frequencies of protons for magnet resonance experiments

摘要

A method for automated determination of the resonant frequency or of the resonance frequencies of a core for magnet resonance experiments with the steps of:– Receiving at least one signal, in particular a fid,– Fourier transformation of the signal to a spectrum (10), which consists of elements and as a vector (v) can be displayed,– Carrying out an analysis of the spectrum (10), wherein at least two means of cross-correlation coefficients (c₁₁, c._1r, k₁₁, k_1r, k_tr) at least one model spectrum (13) with the measured spectrum (10) are determined,characterized in thatin front of the analysis of the spectrum (10) a spectrum - matrix (s) with at least two vectors (v''_i, v''₁, v''₂, v''₃, v''_r) is determined, wherein each vector (v''_i, v''₁, v''₂, v''₃, v''_r) the spectrum - matrix (s) is formed, in that the spectrum (10) is completely or partially for the formation is used and the at least two means of cross-correlation coefficients can be determined in which the at least one of the model (13), which is present as a vector, with the spectrum - matrix (s) is multiplied.
