New App Replaces Ultrasound with Smartphone Camera to Measure Heart Health

Professor Morteza Gharib and colleagues including alumni Derek Rinderknecht (PhD '08), Niema Pahlevan (PhD '13), and Peyman Tavallali (PhD '14) and Caltech visitor in medical engineering Marianne Razavi have demonstrated that the camera on your smartphone can noninvasively provide detailed information about your heart's health. "In a surprisingly short period of time, we were able to move from invention to the collection of validating clinical data," says Professor Gharib. [Caltech story]
