Paper Abstract

A fiber optical strain gauge sensor for detection of respiration motion and heart beat rhythm has been developed in order to suppress motion artifacts in magnetic resonance images (MRI) by gating and triggering procedures. A photoelastic sensing principle has been used in this sensor. It has been adapted to optical fibers to achieve a remote evaluation of the optical signals. The sensor properties are discussed and first results on image quality improvements by the application of this optical sensor are presented for the case of 2 Tesla magnetic resonance imaging of the beating human heart.
