Report from Biomedical Optics Symposium (BiOS)/Photonics West--Part 1

Tonight's Hot Topics session packed a lot of information—and innovation—into just over 2 hours. It included a tribute not originally planned, but certainly appropriate, in honor of Britton Chance, who passed away in November 2010. Bruce Tromberg (University of California Irvine) and Arjun Yodh (University of Pennsylvania) concluded their homage to the prolific researcher by proposing a new unit of measurement: the Britton Chance Unit (BCU), equal to 100 milliwatts/square cm, which is the maximum exposure intensity for biological tissue damage.

Tomorrow (Sunday) will see the unveiling of an International Microcirculation Imaging Lab by a panel of researchers from key facilities in Europe and North America. “The vital role of the microcirculation in every organ of the body provides extraordinary opportunities for health impact, especially personalized healthcare,” says Martin Leahy, a conference chair. He explains that the ability of optical technologies to now provide “exquisite 3D images of the smallest blood vessels at clinically important depths,” enable detection of changes before any clinical signs, and prediction the onset of blindness and ulceration.

Also on the agenda for Sunday is an invited presentation by the Northwestern University team that recently proved able to detect early signs of lung cancer in humans by examining cells scraped from the patients’ cheeks.
