....................... is used to generate X-ray.

  • A.Anger tube
  • B.West tube
  • C.Mayer tube
  • D.Coolidge tube

Answer: D

X-rays are generated with a Coolidge tube.

The Coolidge tube, introduced by William Coolidge in 1913, is the standard X-ray tube. A heated tungsten filament (cathode) emits electrons, which are accelerated through a high vacuum by a high voltage and strike a metal target (anode); their sudden deceleration and the excitation of the target atoms produce X-rays.

The Anger camera is a gamma camera for detecting radiation in nuclear medicine, not a source of X-rays, and 'West tube' and 'Mayer tube' are not X-ray tubes.
