摘要：
The invention concerns an x-ray tube having a thermionic emitter and a warning means, which exhibits means for measuring as least one electrical property of the thermionic emitter and produces a signal during analysis of the measured electrical property, if the measured electrical property shows a value indicating an impending failure of the thermionic emitter.
