Messungen der Atembewegung mit schneller Magnetresonanztomographie und induktiv gekoppelten Markerspulen

Volunteer studies with the marker coil showed a good agreement with simultaneously acquired breathing belt data and position information extracted from the MR images. Whereas the breathing belt provided reliable data only within a certain dynamic range, the marker coil could detect also extreme breathing excursions with a precision better than 2 millimeters.
