A system (100) and method (300) to predict a failure of an imaging system (105) that includes a radiation source (110) having an x-ray tube assembly (115) is provided. The system (100) includes a storage medium (155) having a plurality of programmable storage instructions to instruct a processor (150) to perform the steps of acquiring an age of the x-ray tube assembly (115), calculating a baseline probability of a survivability of the tube assembly (115) for a remaining time period dependent on the age of the tube assembly (115), acquiring measurement of at least one operating parameter of the x-ray tube assembly (115), and automatically changing the baseline probability of a survivability of the imaging system (105) for the remaining time period in response to the measurement of the at least one operating parameter of the x-ray tube assembly (115).
