Abstract

A computed tomography system has a gantry rotating around a patient acceptance space in a stationary gantry housing, the gantry carrying an x-ray radiator connected to a cooling device. The x-ray tube is a directly cooled rotating bulb tube whose coolant serves as an intermediate heat store and which is cooled in standstill periods of the gantry by a likewise co-rotating heat exchanger via a coolant pump.
