摘要： The present invention relates generally to nuclear magnetic resonance tomography (synonym: magnetic resonance tomography—MRT) as used in medical applications for examining patients; it relates in particular to a calibrating method when there is FOV displacement within a plane through angle-dependent modulating of the phase of the Fourier DC point of the respective read-out direction in MRT imaging for determining the device-specific dependency of the time delay requiring to be compensated between the reference signal effecting modulation and the read-out measuring data points of the respective read-out direction of settable measurement parameters.
