Quality Assurance

Question 1

This deck is about factors that influence the

Answer 1

Intensity and quality of the X-ray beam.

Question 2

The quality of RADIATION measures

Answer 2

The beam’s energy

Question 3

The intensity is a measure of the number of

Answer 3

X-RAY photons

Question 4

The intensity of the beam represents the amount or quantity of ______ produced

Answer 4

Radiation

Question 5

What is directly proportional to the intensity of the X-RAY beam

Answer 5

The height of the bremsstrahlung curve (amount of radiation) is directly proportional to the intensity of the X-RAY beam

Question 6

What does HVT or HVL stand for

Answer 6

Half-value thickness or half-value layer of a beam of radiation

Question 7

What is the Half-value thickness of a beam of radiation

Answer 7

It is the amount of a given material which will reduce (attenuate) 50% of the intensity of the X-RAY beam. In other words the special thickness that attenuates the beam to 50% is the HVL

Question 8

When a beam passes through a medium it’s attenuation (reduction) or change in number of photons this is described by what formula

Answer 8

Question 9

U in the formula is the

Answer 9

Linear attenuation (reduction) coefficient- the Fran ion of photons that are interactions per unit thickness of attenuator

Question 10

HVL (special thickness that attenuated the beam to 50%) is calculated by

Answer 10

Question 11

The quality of any beam is proportional to its

Answer 11

HVT of any given material

Question 12

In a diagnostic X-ray beam, the maximum bean energy (E-max) will always be equal to the

Answer 12

Generating voltage (kVp) of the X-ray beam

Question 13

Answer 13
