System and method to manage maintenance of a radiological imaging system

A system (100) to predict a failure of an imaging system (105) that includes a radiation source (110) having an x-ray tube assembly (115), the system (100) comprising:

• a storage medium (155) having a plurality of programmable storage instructions;
• and
• a processor (150) in communication with the imaging system (105), the plurality of program instructions to instruct the 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);
• applying a filter to the acquired measurement, the filter configured to remove outlying measurement data representing a deviation from a trend model and modify the measured at least one operating parameter to remove the outlying measurement data;
• acquiring usage data of the imaging system including a type and quantity of images acquired over time;
• predicting a usage of the x-ray tube assembly based on the acquired usage data;
• and
• automatically changing the baseline probability of a survivability of the imaging system (105) for the remaining time period in response to the modified measurement of the at least one operating parameter and predicted usage of the x-ray tube assembly (115).
