ABSTRACT:
A three dimensional guidance system for percutaneous invasive procedures which develops a line of light above a patient's body to indicate the entry point and path of the invasive instrument. Guidance is provided by alignment of the instrument with the line of light. The line is developed at the intersection of narrow beams of light from light sources mounted at one end and one side of the patient's body. The light sources are mounted for rotation about mutually perpendicular axes and means is provided for precise adjustment of each light source relative to the patient's body to accurately position the line of intersection.
