  • Method for determining motion parameters of an object in a magnetic field
    Patent number: 8624596
    Abstract: A method for determining motion parameters of an object by way of at least one coil within a magnetic field adapted for a magnetic resonance based imaging device. Induced pulses are emitted on the coil in order to provide navigator signals that are finally measured in order to provide a spatial position of the object relative to the coil. At least one reference displacement of the object relative to the coil that is spatially and metrically predefined between two positions of the object is generated so that intensity changes of navigator signals at the coil are measured and recorded in a calibration map.
