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. 本发明涉及一种X射线辐射器和一种计算机断层扫描仪。根据本发明的X射线辐射器具有：X射线管，和X射线辐射器壳体，其中X射线管具有抽真空的X射线管壳体、用于发射电子的阴极和用于根据电子生成X射线的阳极，其中X射线辐射器壳体具有X射线管并且在X射线管外具有气态冷却介质，其特征在于，设有用于气态冷却介质的强制对流的压缩机，以冷却X射线管，其中压缩机的吸力侧与压力侧之间的压力比大于1.3。
