In Vivo Measurement of the Human Thorax and Abdomen Surface Using Laser Vibrometry: A New Diagnostic Tool?

Conference paper
Part of the Conference Proceedings of the Society for Experimental Mechanics Series book series (CPSEMS)

Abstract

Single point laser vibrometry has been used in the past to measure heart pulses. The application of laser measurements in medical applications makes it possible to measure even very small vibrations without contacting the skin surface. In the present work we investigated the possibility to use a scanning vibrometer in order to measure the wave produced on the thorax and abdomen region by the heart beat and blood pressure. In order to trigger the scanner cardiac signals were used. The proposed procedure is intended to be used in the future for detecting anomalies in the human body such as aortic aneurisms. We review some of the practical aspects of the measurement procedure and discuss preliminary results.
