Abstract:
A portable, cervical-cancer detection apparatus comprising a camera having fixed-focus optics, an optical axis associated with the fixed-focus optics, a focal point associated with the fixed-focus optics and lying a predetermined distance from the camera, the apparatus further comprising a processor, a display monitor, and first and second light sources attached to the apparatus and spaced from said optical axis of the camera, the light sources being co-planar with said optical axis and operable to emit first and second energy beams which produce first and second spots upon contacting cervical tissue of a patient, the first and second light sources being oriented so that the first and second energy beams intersect on said optical axis at the focal point of the camera, whereby as the apparatus is aimed at cervical tissue of the patient the first and second spots converge at the focal point thereby insuring that the cervical tissue is properly focused in the camera.
