Paving the way for a digital X-ray and health-care revolution

Professor Karim S. Karim has patented an innovative technology to create a digital X-ray imager that can be built by a typical flat-panel display manufacturer. The digital X-ray imagers currently on the market are expensive (about $50,000 to $100,000 each) since specialized facilities with highly technical equipment are required to manufacture them.
