The Xenox M100 is a fully digital, motor-driven mobile x-ray with an amorphous silicone flat panel. In the Xenox M100, the High Frequency Stable Operating Technology provides the stability to generate quadrate waves to give better penetration for the tube. The tube and main unit are protected against overheating by a safety circuit that constantly monitors the tube’s heat capacity.
