    Eye Imaging Technology Breaks Through Skin by Crossing Beams

    Biomedical engineers at Duke University have demonstrated a method for increasing the depth at which optical coherence tomography (OCT) can image structures beneath skin. The gold standard for imaging and diagnosing diseases within the retina, OCT has yet to find widespread use as an imaging technique for other parts of the body due to its inability to return clear images from more than a millimeter beneath the skin’s surface. Duke researchers found that tilting the light source and detector used in the technique increases OCT’s imaging depth by almost 50%, putting skin diagnoses within reach. The “dual-axis” approach ...
