Researchers tackle cervical cancer with stereovision

Quantitative imaging may aid diagnosis

Kevin Robinson

Each year, more than half a million women are diagnosed with cervical cancer — the second most common cancer in women. As with most cancers, catching it early is the main key to successful treatment. The gold standard for screening is the Pap test, which is not readily available in developing countries. Researchers at Hong Kong University of Science and Technology are working on an optical method for detecting and analyzing cervical neoplasias that often lead to the disease. The method relies on using the acetowhitening effect and a motion canceling stereovision system. “Colposcopy is the...Read full article

    holographic grating
    The generation of a grating on a blank by the holographic process. A series of interference fringes, corresponding to the grooves of the desired grating, are recorded on a photosensitive layer, and the subsequent chemical treatment forms a modulated profile on the surface of the blank by selective dissolution.
    microscope
    An instrument consisting essentially of a tube 160 mm long, with an objective lens at the distant end and an eyepiece at the near end. The objective forms a real aerial image of the object in the focal plane of the eyepiece where it is observed by the eye. The overall magnifying power is equal to the linear magnification of the objective multiplied by the magnifying power of the eyepiece. The eyepiece can be replaced by a film to photograph the primary image, or a positive or negative relay...
