A piezoelectric respiratory monitor for in vivo NMR.
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.
