ABSTRACT:
An arrangement and a method for reducing movement artifacts in spatially resolved magnetic resonance measurements are proposed. A marker system which can emit or reflect at least one electromagnetic ray bundle is permanently connected to a measurement object. The electromagnetic ray bundles emanating from the marker system are projected by means of an imaging system onto spatially separated detector fields and movements of the measurement object are detected by means of the signals of the detector fields and by means of a triangulation method. A correction device generates a correction signal which correspondingly influences the magnetic resonance measurement. Also proposed is a marker system which has a mouthpiece and one or more hollow bodies which can reflect electromagnetic rays and are filled with a material which is visible during a magnetic resonance measurement.
