  • Magnetic resonance imaging system and operating method therefor
    Publication number: 20070085536
    Abstract: In the operation of a magnetic resonance system, an RF excitation coil emits an excitation pulse such that nuclei in an examination subject are excited to emit of magnetic resonance signals. A number of local coils acquire the magnetic resonance signals emitted from the examination subject, with the magnetic resonance signals acquired by the local coils being coded in frequency space. An evaluation device accepts the magnetic resonance signals acquired by the local coils or accepts intermediate signals derived therefrom via one transmission channel per signal, and corrects the accepted signals using correction signals. The evaluation device uses the corrected signals reconstructing an image of the examination subject. The evaluation device determines the correction signals for all signals to be corrected using the same reference signal.
