  • Optical device for measuring small dimensions in vivo
    Patent number: 5933223
    Abstract: A device to measure the relative location in three dimensional space of anatomical structures by injecting a beam of light into an optical imaging device and projecting the beams of light onto the object being imaged. By virtue of the change in the image of the light beam, as a function of changes in the position and/or direction of the injected beam, and knowing the optical transfer function of the imaging device, the position of the anatomical structure can easily be calculated.
