... Introduction In 1895 Wilhelm Conrad Roentgen was experimenting with light when he unexpectedly discovered a new form of electromagnetic energy that he called X rays. Roentgen found that the rays could penetrate a person's hand, and the outline of bones could be seen on a chemically coated fluorescent screen behind the hand. Roentgen then replaced the screen with photographic film to make lasting pictures of the images. Radiography studies are being replaced by digital (computerized) examinations. Today, x-ray studies are often performed as the initial examination to diagnose a wide variety of diseases and injuries that is beneficial in the medical industry today. This research seeks to provide information on the uses of x-rays in radiotherapy and imaging. It seeks to provide a well informative research on what is radiotherapy, the applications of x-rays, the uses of x-ray in radiotherapy and imaging. Acknowledgement Firstly I would like to thank God
