Fundamentals of X-ray imag<strong>in</strong>g Cardiology department, SVCMC
Generator and X-ray tube X-ray tube is a vacuum tube Electrons:generator to the cathode, white-hot (about 3,000 000°F) F). Electrons virtually boil off the cathode at this temperature (thermionic emission) jump from the cathode to the anode by the large voltage potential across the X- ray tube. The maximal (peak) voltage potential across the X-ray tube is referred to as the kVp of the system. cup sets up a local voltage potential - focus and control the number of e The number of electrons sent from the cathode to the anode is referred to as the mA of the system and directly correlates with the eventual number of X-rays produced.
