housing
- Cathode & Anode
- Collimator
Anode - answer - Electrons strike the metal anode where they create X-
rays
Cathode - answer - Source of free electrons. Electrons leave the cathode
and are accelerated toward the anode where they create X-rays.

Collimator blades
, What can "collimating down" or "coming down" do for the patient? -
answer - Reduces patient radiation exposure
- Reduces the amount of radiation to which operator and staff are
exposed
What is the maximum X ray energy determined by? - answer kVp
What is the inverse square law? - answer The intensity of a beam of X
rays decreases rapidly as you move away from it. The intensity of an X-
ray beam decreases with the square of the distance from the X-ray
source
What is attenuation? - answer Anything that is in the X ray beam path
that will further reduce the intensity of the X ray beam. Attenuation of
an X-ray beam increases with increasing tissue thickness.
What is Compton scattering? - answer An interaction between an X-ray
and a bound electrons
Which type of tissue will require more attenuation? - answer Bone
tissue > Soft tissue
What is Beam hardening? - answer The selective removal of low energy
X rays from an X ray beam because it is most likely to be attentuated
