 Abstract: In this work, 19F NMR field probes are used to track subject head motion and field fluctuations due to motion and breathing at a 9.4 T human scanner. The field probes are rigidly attached to the subject’s head via a bite bar. A custom made transmit/receive chain using a PCB and external signal processing prevents the use of scanner receive channels. With this setup, position measurements are possible with a standard deviation of 57 µm or smaller depending on the axis as well as field measurements with a standard deviation of 3 Hz.
