A fiber optic reflectometer, capable of monitoring physiological parameters in a high magnetic field without significant disturbance of either rf or static fields, is described. Both cardiac and respiration rates were monitored with this optical device while 31 P NMR spectra of the liver of an anesthetized rat were acquired. © 1986 Academic Press, Inc.
