The Xoft model s700 miniature x-ray source operates at up to 50 kVp and 300 μA and is similar in size and dose rate than a radioactive high-dose-rate 192Ir source. Photo courtesy of Xoft, Inc (Fremont, California).

Detail of the Xoft model s700 x-ray source. The high-voltage (HV) cable (purple) creates a 50 kVp potential between the cathode (green) and the anode (blue). Electrons emitted from the filament (green) accelerate down a vacuum tube (yellow) to impact the tungsten target (red) and release x-rays. Heat generated by the 15 W process is carried away by the encapsulating cooling sheath (gray). Diagram courtesy Xoft, Inc. (Fremont, California).
