Beam quality refers to:

• the energy level of the radiation

• the amount of radiation

• how useful the radiation is

• all of the above

The primary controlling factor for beam quality is:

• mAs

• kVp

• distance

• filtration

As the kVp increases:

• beam energy decreases

• beam energy increases

• beam penetrability increases

• B and C

A higher energy beam is said to be:

• soft

• hard

• weak

• powerful

Placing filtration in the path of the beam results in:

• a harder beam

• a softer beam

• more x-ray photons

• a sharper image
