Abstract

A housing (30) surrounds at least a portion of an x-ray tube (1). A cooling system (32, 32′) supplies a cooling liquid through the housing. The cooling system includes a pump (40, 40′) and a flow sensor system (60, 60′) which measures a pressure difference across the pump. A processor (80, 80′, 82, 82′) determines a cooling fluid flow rate from the pressure difference. A controller (81, 81′, 82, 82′, 107) 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.
