An efficient needle injection technique and radiological guidance method for percutaneous procedures

This paper presents a simple radiologicd image guidance method and robotic system optimized for percutaneous procedures. This simplicity is achieved by combining the proven guidance procedure normally employed by practicing surgeons with a simple and cost-effective needle injection device. The needle injector exhibits an extremely low radiological profile while providing actuated needle motion. The mechanical manipulator is designed to be used stand-alone in existing operating rooms without additional computers or personnel.
