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. 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. 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. 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. 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. 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.

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.  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.
