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.
