Abstract
A housing () surrounds at least a portion of an x-ray tube (). A cooling system (') supplies a cooling liquid through the housing. The cooling system includes a pump (′) and a flow sensor system (′) which measures a pressure difference across the pump. A processor (′) determines a cooling fluid flow rate from the pressure difference. A controller () limits operation of the x-ray tube based on the cooling fluid flow rate and a measured temperature of the cooling fluid to prevent x-ray tube overheating while minimizing cooling time between x-ray tube operations.
