Paper Abstract

The criteria determining thermal loading of x-ray tubes is reviewed. Major parameters of maximum rated heat storage capacity and maximum continuous dissipation are defined as related to the thermal characteristics of the x-ray tube target and its radiographic loadability. The resulting anode thermal characteristic chart is proposed and provides for a 25% target storage capacity value on which to base radiographic ratings. For procedures in which the target heat storage exceeds 25% of the maximum rated storage capacity, a reduction to 0.8 of the maximum radiographic load rating is proposed. A target design capable of withstanding greater thermal loads and results of qualification tests are reviewed.
