Novodaq has been using fluorescence imaging to identify cancer cells for years, but with endoscopy. [1] They bought a company called Xillix who brought the technology to market in the early 2000's. [2] Xillix was created from some technology out of the University of British Columbia in the late 1980's. [3]

Putting this into glasses is very cool, makes one wonder why Novodaq didn't do this.
