Abstract

A temperature supervisor (10) for an X-ray tube comprises a processor (12) configured to: receive tube operational data (16) during use of the X-ray tube in an X-ray imaging system, wherein the tube operational data comprises a voltage and/or current and/or power applied to the X-ray tube; process the received tube operational data to determine a present temperature of a component of the X-ray tube; receive mechanical load data (18) during use of the X-ray tube, wherein the mechanical load data relates to a present mechanical load on the component. In accordance with the invention, the mechanical load data is used to determine a present temperature limit for the component, wherein the present temperature limit is dynamic and dependent on the present mechanical load on the component. The determined present temperature of the component is compared with the determined present temperature limit of the component to output an alarm signal (21) for alerting a user and/or a safety control signal (22) for controlling operation of the X-ray tube, if the determined present temperature of the component is higher than the determined present temperature limit of the component. The temperature supervisor (10) provides safety in combination with high-performance utilization of the X-ray tube in that the dynamic temperature limit depends on the mechanical load on the X-ray tube component and therefore allows to take co-dependency between mechanical load and maximum thermal load into account.
