A piezoelectric respiratory monitor for in vivo NMR

Magn Reson Med. 1992 Oct;27(2):338-42. doi: 10.1002/mrm.1910270213.


This report describes a simple electronic device employing a piezoelectric element which serves as a sensitive detector of motion. The device is useful as a monitor of respiratory motion for nuclear magnetic resonance animal experiments in vivo. It can also provide a trigger pulse for respiratory gating experiments.
