rt20 worksheet 9-2

a radiographic tube has 0.5 mm Al inherent filtration, 1.0 mm Al added filtration, and 1.0mm Al filtration in the light-localizing collimator. therefore, the total filtration is?

2.5 mm Al

which of the following is the most appropriate measure of x-ray quality?

HVL

the quality of an x-ray beam is principally a function of which of the following?

KVP

the HVL is defined as?

a thickness of attenuator that will halve x-ray quantity

to measure HVL, which of the following is required?

aluminum absorbers

a representative radiographic tube has 0.5 mm Al inherent filtration and 2.0 mm Al added filtration. therefore,

an additional 1.0 mm Al filtration will harden the x-ray beam

the HVL is affected principally by a change in?

filter thickness

if increasing the kvp increases the hvl, x-ray quantity will?

increase by kvp^2

adding filtration to an x-ray beam will do which of the following?

increase x-ray quality

added filtration affects the x-rays beam in what way?

increased beam hardening

as filtration is added to an x-ray beam?

low-energy x-rays are removed more readily than high-energy x-rays

it is often stated that mas controls quantity and kvp controls?

quality

when filtration is added to an x-ray tube, what increases?

radiation quality

reducing kvp will do which of the following?

soften the x-ray beam

an increase in mas will increase which of the following?

x-ray quantity
