Question 7.
Discrete emission spectrum

ANSWER
illustrates characteristic x-ray production, x axis is the x-ray energy and the y axis is the number of each type of x-ray photon

, Question 8.
Characteristic photons

ANSWER
produced when outer-shell electrons fill inner-shell vacancies in atoms and are named for the shell being filled regardless of the shell involved representing
the energy variation depending on what shell is involved



Question 9.
Continuous emission spectrum

ANSWER
illustrates brems x-ray production, x axis is the energy, y axis is the number of photons, creates a bell shaped continuum



Question 10.
Primary beam

ANSWER
refers to the x-ray beam as it is upon exiting the collimator and exposing the patient



Question 11.
Remnant beam

ANSWER
refers to the x-ray beam that remains after interaction with the patient and is exiting the patient to expose the image receptor



Question 12.
transmitted photons

ANSWER
those exiting the patient without having interacted with anatomic structures



Question 13.
scattered photons

ANSWER
those that have lost energy and have been redirected after interacting with anatomic structures



Question 14.
Half value layer (HVL)

ANSWER
measurement for beam quality, defined as the thickness of absorbing material necessary to reduce the energy of the beam to one-half its original intensity



Question 15.
What is the normal HVL of diagnostic beams?

ANSWER
3-5 mm Al
