  1. 3. another term for radiotherapy.
  2. 5. Medical imaging is the technique and process of imaging the interior of a body for clinical analysis and medical intervention,
  3. 6. a system for detecting the presence, direction, distance, and speed of aircraft, ships, and other objects, by sending out pulses of radio waves which are reflected off the object back to the source.
  4. 8. radiation"
  5. 10. the maximum extent of a vibration or oscillation, measured from the position of equilibrium.
  6. 12. Information and communications technology is an extensional term for information technology that stresses the role of unified communications and the integration of telecommunications and computer
  7. 13. an electromagnetic wave of high energy and very short wavelength, which is able to pass through many materials opaque to light.
  8. 14. (of electromagnetic radiation) having a wavelength just greater than that of the red end of the visible light spectrum but less than that of microwaves. Infrared radiation has a wavelength from about 800 nm to 1 mm, and is emitted particularly by heated objects.
  9. 15. the entire range of wavelengths of all known electromagnetic radiations

  1. 1. he distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave.
  2. 2. radiation of a kind arising from the radioactive decay of atomic nuclei.
  3. 4. (of electromagnetic radiation) having a wavelength shorter than that of the violet end of the visible spectrum but longer than that of X-rays.
  4. 7. the rate at which something occurs over a particular period of time or in a given sample.
  5. 9. an electromagnetic wave of a frequency between about 104 and 1011 or 1012 Hz, as used for long-distance communication.
  6. 11. an electromagnetic wave with a wavelength in the range 0.001–0.3 m, shorter than that of a normal radio wave but longer than those of infrared radiation. Microwaves are used in radar, in communications, and for heating in microwave ovens and in various industrial processes.
  7. 16. a particle representing a quantum of light or other electromagnetic radiation. A photon carries energy proportional to the radiation frequency but has zero rest mass.
