摘要： A brazed X-ray target includes a metallic cap and a graphite back including a nonlinear record groove attached thereto along a stepped surface. An upper corner joint of the stepped surface is distanced from a cap outer edge and a focal track where the maximum heat is generated during use of the target. The graphite back is extended outward toward the cap outer edge to increase a thermal storage of the graphite, and a recess is formed into the cap to maintain a selected moment of inertia of the target and thereby maintain the rotordynamics of a given X-ray tube.

摘要： Possible failure of x-ray tubes is predicted by monitoring and analysis of operating parameters considered leading indicators of failure. Historical data for a tube population is analyzed by discriminant analysis to develop a failure prediction algorithm. The algorithm is used to correlate operating parameters, or values derived from the operating parameters with a potential for tube failure. The operating parameters may include anode overcurrent events and spits, or spit rate exceeded errors for a diagnostic system in which the x-ray tube is installed.
