X ray machine-new

  1. 1. Presented by:Aaditee. S. KulkarniOmkar. R. HaldonkarPranali. N. KulkarniGanesh M. Nair
  2. 2. What are x rays?  Electromagnetic radiations.  Wavelength 0.01 to 10 nanometers.  Can penetrate some solids and liquids, and all uncompressed gases.  Used for diagnostic radiology.
  3. 3. Three major elements of an x-ray machine:1.Vacuum tube: made up of Pyrex glass. tungsten anode is enclosed along with cathode. cathode or emitter.
  4. 4. X-ray tube Cathode accelerates electrons and leads them to anode(electron beam). Only a small portion of the electron beam is converted to x rays. Photons are discharged in all directions. By adjusting current and voltage, we can direct the beam on a visible substance.
  5. 5. Rotating Anode The anode of rotating anode tube consist of a large disc of tungsten, or an alloy of tungsten, which theoretically rotates at a speed of about 3600 rpm. The purpose of rotating anode is to spread the heat produced during an exposure over a large area of anode.
  6. 6. 2.High Voltage Power Source A transformer is used Alternates between the voltage of currents being sent to the emitter or to the anode. Emitter requires small voltage supply for small currents Anode needs a large voltage supply
  7. 7. 3. Operating Console Control unit.. Manages current, voltage and timer. Current control allows adjustment of tube current to vary radiation intensity. Voltage control allows adjustments in anode to change energy of radiation. Timer determines the duration of exposure.
  8. 8. X ray machine
  9. 9. Working of x-ray tube: Cathode accelerates electrons and leads them to anode(electron beam) Only a small portion of the electron beam is converted to x rays Photons are discharged in all directions By adjusting current and voltage, we can direct the beam on a visible substance
  10. 10.  Advantages:- It is non-invasive.- It can be made available as a portable x-ray unit.- It is less costly when compared to the other imaging modalities like MRI or CT. Limitations:- X-ray uses radiation, which can cause cancer if you are exposed to it over a prolonged period of time.- Do not provide as much information as MRI and CT.
  11. 11. APPLICATIONS Orthopantomogram: all teeth Mammogram: breast tissues Fluoroscopy for real time images
  12. 12. Medical purposes Radiography Dentistry
