X-Ray Tube Heating and Cooling - sprawls.org

If excessive heat is produced in the x-ray tube, the temperature will rise above critical values, and the tube can be damaged. Although the joule is the basic unit for energy and heat, it is not always used to express x-ray tube heat. However, anodes in some high powered equipment, such as that used in CT, are cooled by the circulation of oil through the anode to a heat exchanger (radiator).
