Chapter-06 X-ray Production by Thayalan Kuppusamy (2017) Edition : 2/e

X-rays were discovered by WC Roentgen, the German physicist in 1895, when he was investigating the conduction of electricity through gases at low pressure in glass tubes. X-rays are produced when fast moving electrons are stopped by means of a target material. The moving electron possesses kinetic energy equal to ½ mn2, if m and v are the mass and velocity o...

Chapter-07 X-ray Tube Technology by Thayalan Kuppusamy (2017) Edition : 2/e

This chapter basically talks about the X-ray tube technology. In earlier periods, gas tubes were used to produce X-rays. But these tubes had lot of disadvantages. Hence, Coolidge proposed a prototype X-ray tube based on the thermionic emission principle. On the basis of Coolidge tube, several X-ray tubes have been designed. The stationary anode X-ray tube is... [More]

Wilhelm Roentgen’s reported X-rays in 1890. Today, imaging with X-rays is perhaps the most commonly used diagnostic tool with medical profession. X-ray unit is in fact a life line of any working hospital. This chapter carries information on x-rays tube and its maintenance and working of x-ray machine with electric circuit. Further, mechanism of X-rays produc... [More]
