Abstract:
1. A method ( 300 ) to predict a failure of an imaging system ( 105 ) that includes an x-ray tube assembly ( 115 ) as a radiation source ( 110 ), the method ( 300 ) comprising: acquiring an age of the x-ray tube assembly ( calculating a baseline probability of a survivability of the tube assembly ( acquiring measurement of at least one operating parameter of the x-ray tube assembly ( 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 probability of a survivability of the x-ray tube assembly (
