Ultrasound Strain and Time-of-Flight for Diagnosing Pneumonia
Jonathan Rubin of the University of Michigan in the U.S. will develop a simple, low-cost ultrasound device with cell phone display that can diagnose children with co-existing pneumonia and malnutrition. Over two million children per year die from pneumonia, and many of these deaths are caused by coexisting malnutrition. They will design an ultrasound stethoscope device to automatically measure lung expansion and contraction during breathing to detect ventilation problems caused by pneumonia as well as the levels of subcutaneous fat on the chest wall to detect malnutrition. The device will be tailored for use by a minimally-trained health worker and the results reported on the display by a numeric readout. They will test the adapted ultrasound device in the laboratory, and gather population data to determine the normal distribution of fat thickness in the chest wall for estimating nutritional status.
