Abstract

One instrument used in clinical medicine to create a high-contrast image of the body's soft tissues involves the principle of nuclear magnetic resonance. The machine is called a magnetic resonance imager (MRI). The MRI scanning process is analogous to optical devices in that it is somewhat sensitive to vibration. This paper describes some field tests intended to quantify the effect of vibration upon image quality as heavy vehicles passed near two on-grade MRI installations. The measured field data are compared to recently published criteria and also are correlated with test images created by the MRI during the vibration events. The paper includes recommendations for improving the format of the manufacturer's vibration specification.
