Hf - excitation with two resonance frequencies for the detection of the cest - effect by means of a magnetic resonance system

摘要

The invention relates to a hf - excitation (25) with two resonant frequencies (f₁, f₂) for the detection of the cest - effect by means of a magnetic resonance system (5). In this case, the hf - excitation (21) with the aid of a first hf - antenna (4) and a second hf - antenna (4 '') of the magnetic resonance system (5) is realized in that with the first hf - antenna (4) a first part of the hf - excitation (25) with a first resonant frequency (f₁) the two resonance frequencies, and with the second hf - antenna (4 '') a second part of the hf - excitation (21) with a second resonant frequency (f₂) the two resonant frequencies is carried out.
