Quantitative Monitoring Wound Healing Status Through Three-dimensional Imaging on Mobile Platforms

J Am Coll Clin Wound Spec. 2017 Dec 14;8(1-3):21-27. doi: 10.1016/j.jccw.2017.11.001. eCollection 2016.

Abstract

There are approximately 6.5 million patients in the U.S. suffering from chronic wounds and approximately 140,000 patients hospitalized every year with new wounds. With a long healing process, this demands the need for a non-contact, low cost, and remote monitoring solution that can assist clinicians in diagnosing and treating a patient's wound. This will reduce the burden of countless office visits, especially for those who are elderly and incapacitated. We present a mobile platform based wound 3D imaging app. The app is the only integrated measurement solution encompassing wound area and volume through low cost yet accurate 3D imaging. Extensive experiments show the app has 1.14% and 4.41% relative errors for wound area and volume measurement respectively, far exceeding currently employed clinic methods. In addition, non-invasive volume measurement methods currently use expensive industrial 3D (>$20K) cameras, but our solution provides cheap and accurate results.
