About this technology

Overview

NASA Langley Research Center has developed an infrasonic stethoscope that detects a broader range of physiological conditions than conventional stethoscope, use of which has declined mainly due to availability of other advance technologies such as the echocardiogram. The echocardiograms can be complex, costly and require the need of a specialist for correct interpretation. Further, it is estimated that more than 85% population of the world does not have access to advanced diagnostic tools such as echocardiogram and CT scans. This scope provides additional data to physicians by monitoring signals across full frequency bandwidths that include cardiac, carotid artery, and respiration activities something that is not available in conventional stethoscopes.
