Primary Beam X-rays that are produced by the tube and strike the patient.
Comprised of either bremsstrahlung and/or characteristic
Remnant Beam The x-ray beam that remains after interaction with the patient and is exiting the
patient to expose the image receptor.
Made up of primary and secondary radiation.
Scatter radiation increases as ___________________ increases. field size
Scatter radiation A type of secondary radiation that occurs when the beam intercepts an object,
causing the x-rays to be scattered.

What is the controlling factor of quality? kVp
If you increase kVp what is the effect on quality? It increases
What determines the quantity of x-ray photons? mAs
What happens to patient exposure when the mA is It increases
increased?
More x-ray photons (mA) means.... More patient dose
