Abstract: A technique for scheduling planned maintenance of equipment, such as medical imaging systems, permits selection of time-based or usage-based scheduling. If usage-based scheduling is selected, operational data collected from the systems serves as the basis for computing a maintenance schedule along with reference usage values for parameters indicative of use. Reference may be made to norms for similar equipment, and the schedule may be adapted accordingly. Trends in usage, increasing or decreasing, may be accommodated by comparison of the usage determinations over time, and schedules may be adjusted accordingly.

Abstract: 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.
