ACTUAL EXAM WITH ANSWERS.
As KVP , a greater potential difference exists between the cathode in
the anode - correct answer -Increases
An electron approaching a positive nuclear charge changes direction and loses
energy - correct answer -Brems radiation production
An x-ray to the inner target needs to have a number
and a point - correct answer -High atomic
High melting
True or false
the cathode assembly receives both low and high voltages - correct answer -
True
High scale contrast = - correct answer -Short scale contrast
CRs use while DRs do not - correct answer -IPs
The term is used to describe how much of the patient is included
in the matrix - correct answer -FOV
,2
What permits the flow of current in only One Direction? - correct answer -A
rectifier
,3
As the increases, the electrons from the cathode
strike the anode in greater numbers and with greater energy - correct
answer -Potential difference
As a Kvp increases a greater potential difference excists which results in an
increase level of production of wavelength and high-energy radiation -
correct answer -Short
KVP's affect on density is governed by what? - correct answer - 15% rule
A increases in KVp of 15% density - correct answer -Doubles
A decrease in KVp by 15% density - correct answer -1/2s
Intensity of the x-ray beam is inversely proportional to the square of the distance
between the source of x-rays and the image receptor - correct answer -Inverse
square law
, 4
Intensity is measured in - correct answer -Roentgens
Or
coulombs/kilogram (SI)
Radiographic density is a function of what? - correct answer - Beam intensity
Beam intensity is governed by the? - correct answer -Inverse square law
The inverse square law describes changes in -
correct answer -Beam intensity
(and radiographic density which is a function of being intensity)
If the SID is doubled intensity (density).... - correct answer - Decreases four times
