Research abstract
THIS PROPOSAL IS FOR THE DEVELOPMENT OF PRECISION TRANSDUCERS FOR USE IN AN ELECTRONIC STETHOSCOPE AND AN ACCELEROMETER FOR MEASUREMENT OF VASCULAR SOUNDS GENERATED BY STENOSES AND ANEURYSMS, FETAL HEART RATES AND TISSUE MOTION. THE INSTRUMENT WILL INCLUDE AN INFRARED DATA TRANSMISSION LINK FOR WIRELESS TRANSMISSION OF TRANSDUCER SIGNALS. A MAJOR GOAL WILL BE TO IMPROVE THE SIGNAL TO NOISE RATIO OF THE SYSTEMS USING ACTIVE AMBIENT NOISE CANCELLATION. A PRELIMINARY MODEL SYSTEM HAS BEEN BUILT AND DEMONSTRATED TO BE FEASIBLE FOR DEVELOPMENT OF INSTRUMENTS WITH THE NECESSARY SENSITIVITY AND SELECTIVITY. MEDICAL ACCEPTABILITY CONSIDERATIONS WILL BE PROVIDED BY A CONSULTANT PHYSICIAN.
