X-ray

  1. 1. Group 6 “X-ray”
  2. 2. Definition Wavelength & frequency Inventor Application Conclusion
  3. 3. Definition • X-ray light is very strong and is not visible to human eyes • That rays can penetrate objects opaque. X-rays are commonly used to look at something we cannot see directly. • X-rays or Roentgen rays are a form of electromagnetic radiation • X-rays are commonly used in the diagnosis of medical images and X-ray crystallography. • X-rays are a form of ionizing radiation and can be dangerous.
  4. 4. Wavelength • The wavelength ( ) of x-ray range 10 nanometers to 100 picometers (with frequency 1016 Hz until 1020 Hz). • These X-rays have a shape similar to that of ordinary light rays, infrared and radio waves; differing only in terms of wavelength other features.
  5. 5. Electromagnetic Spectrum
  6. 6. Inventor Wilhelm Conrad Roentgen a physicist at the University of Wurzburg, Germany, was first discovered in 1895 Roentgen rays while experimenting with cathode rays. At that time he saw the onset of fluorescence light from barium crostal platino cyanide the tube Hittorf-Crookes are electrified. He soon realized that this phenomenon is a new discovery that he steadfastly continued on going investigations in the following weeks. Not long after the light was discovered he calls a new light or X-rays only later did people call these rays Roentgen rays in honor of Wilhelm Conrad Roentgen.
  7. 7. Application CT Scanner Bone X-ray machine
  8. 8. Application Linear Accelerator Backscatter X-ray
  9. 9. CT Scanner Computed tomography or CT scan works on the same principles as fixed plate x rays, only with a CT scan, an x ray tube rotates around the individual, taking hundreds of images that are then compiled by a computer to produce a two- dimensional cross section of the body. Although many images are taken to produce a CT scan, the total dose of radiation the individual is exposed to is low.
  10. 10. Schematic of CT Scan
  11. 11. Conclusion • X-ray light is very strong and is not visible to human eyes • That rays can penetrate objects opaque. X-rays are commonly used to look at something we cannot see directly. • The application of x-rays is CT Scanner, Bone x- ray machine, Linear Accelerator, Backscatter X- ray etc.
