The management of mass casualty situations from natural disasters, major accidents, or warfare is jeopardized by the shortcomings of existing X ray tubes used in medical diagnostic imaging less than 12 duty cycle, short life, extreme fragility. In the FINAL REPORT we confirm the feasibility and present the preliminary design of a novel rotating X ray tube with 100 duty cycle even under a full load. The tube is also very rugged because it does not contain a cantilevered anode arrangement nor heat sensitive bearings. The tube also has the built in capability of scanned focus position. With this continuous high power output X-ray tube, containing two discrete focus positions, the spatial resolution of scanned projection imaging can be substantially increased and the replacement of silver based film in projection imaging becomes a realistic possibility. Unlike other suggested solutions this tube is hermetically sealed, requires bo liquid based or other vacuum seals, nor vacuum pump.
