Fiber Optic Device Probes for Early Cancer

Facebook X LinkedIn Email
DURHAM, N.C., March 14, 2006 -- A new device that could use light to harmlessly and almost instantly probe for early signs of cancer has been developed by researchers at Duke University’s Pratt School of Engineering. The device would allow physicians to search for cancer in epithelial cells that line body surfaces, including the skin, lungs and digestive and reproductive tracts, by simply inserting a fiber-optic probe. The team has reported the first clinically practical version of their “angle-resolved low coherence interferometry” (a/LCI) technology designed to diagnose incipient cancer...Read full article

    probe
    Acronym for profile resolution obtained by excitation. In its simplest form, probe involves the overlap of two counter-propagating laser pulses of appropriate wavelength, such that one pulse selectively populates a given excited state of the species of interest while the other measures the increase in absorption due to the increase in the degree of excitation.
