RE: Tissue fluorescence visualization tech for ski I like this - so LED it appears would be using a version of the velscope as a reflectant tool when surgeons are removing a cancerous lesion to better the odds for clear margins.
Interesting. Here is the patent: https://www.google.com/patents/US6021344
"Apparatus for the diagnosis of a skin disease site by visual fluorescence inspection comprising an excitation light source for illuminating the disease site, a light guide for transmitting the excitation light directly to the disease site to generate fluorescence light and viewing goggles for processing the excitation light reflected and the fluorescence light emitted from the disease site to provide a fluorescence image of the disease site to a user. The fluorescence image is used to aid the medical assessment of skin conditions and the diagnosis of cutaneous diseases by supplementing the visual assessment of skin lesions made by the naked eye. The apparatus can be used in several modes of operation that permit the viewing of full color fluorescence images and enhanced two color images. The apparatus can also use image intensifying equipment to amplify fluorescence light so that even very weak fluorescing objects can be seen. A method for acquiring and viewing the fluorescence..."

Just as a comparison - I read over the new patent application for "Rapid multi-spectral imaging metholds and apparatus and applications for cancer detection and localization" US 20130012794 A1 - a good read. I know which patient I would prefer however both may have merit.
time will tell etiher way the I believe the research team to be solid! just my thoughts.
Good luck.
