Fluorescence Imaging 'Video Pill' Made for Cancer Detection

Facebook X LinkedIn Email
A wireless capsule with fluorescence imaging capabilities could be swallowed by patients to aid in detection of cancers of the throat and gut. Previous versions of such "video pills" have relied on illuminating patients' innards using a small light source, restricting clinicians to conclusions based on what they can see in the spectrum of visible light. Now researchers from the University of Glasgow, using an advanced semiconductor single-pixel imaging technique, say they have achieved fluorescence imaging in a small pill form for the first time. Fluorescence imaging is a common...Read full article

    fluorescence
    Fluorescence is a type of luminescence, which is the emission of light by a substance that has absorbed light or other electromagnetic radiation. Specifically, fluorescence involves the absorption of light at one wavelength and the subsequent re-emission of light at a longer wavelength. The emitted light occurs almost instantaneously and ceases when the excitation light source is removed. Key characteristics of fluorescence include: Excitation and emission wavelengths: Fluorescent materials...
