Abstract
A calibration method for calibrating a measuring element for determining an electric current flowing through a basic-field magnet of a magnetic resonance imaging system includes performing a measurement with the measuring element, and performing a frequency measurement in the magnetic field of the basic-field magnet with a frequency measuring unit. The measurement of the measuring element and the frequency measurement are corresponding to the same magnetic field of the basic-field magnet. The calibration method also includes calculating a calibration factor based on a deviation between the measurement with the measuring element and the frequency measurement, and calibrating the measuring element or the electric current in the basic-field magnet based on the calibration factor.
