 So we have an existing program called DEXIS. DEXIS is a digital x-ray program. Now DEXIS has add-on modules of artificial or augmented intelligence where they will pick out, with a keystroke, show me areas of potential decay. They'll pick out areas. They say, look at this area, look at this area, look at this area. So they didn't diagnose it. The doctor's diagnosing it.
