Abstract
A coaxial laser targeting device is provided for use with x-ray equipment. The device includes an x-ray transparent housing, which encloses a gimbal platform that may be adjustably inclined in any direction. A laser source supplies light through an optical fiber to a lens assembly in the center of the gimbal platform and directs light through a laser emitting aperture in the housing. Three adjustment members arranged in a triangular configuration are used to incline the gimbal platform in any direction relative to the housing to angularly align the laser beam with an x-ray beam emitted by the x-ray equipment so that the beams are coaxial. A visible target created by the laser beam on a patient allows surgeons and the like to accurately perform medical operations without the need to continually operate an x-ray machine.
