ABSTRACT
It is essential that any practitioner understands the properties of X-rays and the way in which they are produced. The ability to generate a varied X-ray beam is necessary to produce diagnostic images with optimum a quality and minimum dose. The circuitry of the X-ray tube coverts a mains supply of 415 volts and 13 amps to the range of kilovolts (kV) and tube currents (mA) required to generate a range of X-rays. The circuitry allows an electrically safe process and facilitates exposure times from milliseconds to several seconds. The X-ray tube not only produces a beam of X-rays, but also dissipates the heat produced as a byproduct of the process efficiently, so repeated exposures can be made. It also needs to be electrically safe at the high voltages used.
