OK..Here is the quote from the Velscope website, under "History:" "VELscope is a revolutionary hand-held devicee that provdes dentists and hygienists with an easy-to-use adjunctive mucosal examination system for the early detection of abnormal tissue. The patented VELscope technology platform was developed in collaboration with the British Columbia Cancer Agency and MD Anderson Cancer Center, with funding provided in part by the HIH. It is based on the direct fisualization of tissue flourescence and the chanages in flourescence that occur when abnormalities are present."

At least I did not imagine reading that MDA had had a hand in the development of the VELscope, or at least the "patented technology platform."

I will try to find the link to the MDA site that describes their current work on a newer version of the same instrument.

That's the way with technology, isn't it? It's obsolete before you get it out of the box.
