Abstract
In a method and magnetic resonance apparatus for automated establishing of the resonant frequency or resonant frequencies, especially of protons for magnetic resonance experiments, at least one signal, especially an FID is acquired and Fourier transformed to a spectrum. The number of resonance peaks of the spectrum is determined and the resonant frequency or resonant frequencies are established dependent on the number of peaks.

A method for automated establishment of at least one resonant frequency in a magnetic resonance (MR) scanner, comprising:
- from a control computer, operating an MR scanner to acquire at least one MR signal from a subject situated in the MR scanner;
- in said control computer, Fourier transforming said MR signal to obtain a spectrum;
- in said control computer, determining a number of resonant peaks in said spectrum;
- in said control computer, determining at least one resonant frequency dependent on said number of resonant peaks;
- and
- from said control computer, generating and emitting an electronic signal in a form configured to operate said MR scanner by exciting nuclear spins in said subject at said at least one resonant frequency.
