Summary: | The invention relates to an x-ray emitter and a computed tomography device. An x-ray emitter according to the invention includes an x-ray tube and an x-ray emitter housing, wherein the x-ray tube includes an evacuated x-ray tube housing, a cathode for emitting electrons and an anode for generating x-rays as a function of the electrons; the x-ray emitter housing includes the x-ray tube and a gaseous cooling medium outside the x-ray tube. The x-ray emitter further includes a compressor for a forced convection of the gaseous cooling medium for cooling the x-ray tube, a pressure ratio between theintake side and pressure side of the compressor being greater than 1.3.
