Apparatus and method for determining a physiological movement of an examination subject in a magnetic resonance apparatus

摘要

A device for determining a physiological movement of an examination subject in a magnetic resonance apparatus having a determination unit and a sensor unit is proposed. The magnetic resonance apparatus comprises a magnet for generating a magnetic field. The sensor unit is exposed to the physiological movement and is designed to detect a change and / or a strength of the magnetic field as a function of the physiological movement. The determination unit is designed to determine the physiological movement based on the detected change and / or the detected strength of the magnetic field.
