Abstract
There is disclosed a head-mounted imaging system which system employs a headband to be worn on the head of a surgeon during a surgical procedure. A surgeon may utilize a microscope eyeglass assembly in order for him to achieve a desired magnification of the operating area. The headband assembly includes an imaging system which imaging system furnishes a beam of light which beam of light is reflected into the operating area by means of a tiltable mirror coupled to the headband assembly. The tiltable mirror receives the reflected image from the operating site. This image is received by the imaging system where it is directed through a zoom lens magnification assembly whereby the magnification of the lens assembly is set to correspond to the microscope eyeglass assembly worn by the surgeon. The image thus directed through the zoom lens assembly is then coupled to a television monitor pickup for eventual viewing on a television monitor to thereby enable observers to view the entire operation as if through the eyes of the surgeon.
