Podiatry Xray Exam Questions With Complete Solutions
0.5 rems Correct Answers Annual non-occupational limit
3 basic safety measures Correct Answers Time, distance,
shielding
3 primary exposure factors are adjusted at Correct Answers The
control panel.
3 primary exposure factors Correct Answers mA, time, kVp
5 rems Correct Answers Annual occupational limit
ALARA Correct Answers "As low as reasonably achievable"
Automatic processing Correct Answers Takes about 90 seconds
Back of body Correct Answers Posterior
Beam limitation device Correct Answers Shapes the dimension
of the Xray beam. Always use the smallest exposure field to
reduce patient exposure.
Blurring Correct Answers Cause by patient motion
Contrast Correct Answers Degree of difference between
light/dark areas
Crescent mark Correct Answers Caused by mishandling
, Density Correct Answers Measure of the amount of blackness
on film
Distal Correct Answers Far from attachment of a limb, farther
from the point of origin
Film badges/TLD's Correct Answers Commonly used for
occupational exposure measuring. To be worn on collar. Badges
to be changed every 4 weeks, TLD's every 3 months.
Front of body Correct Answers Anterior
Genetic effects Correct Answers Passed to the offspring
If a film is underexposed, Correct Answers Increase mAs or
kVp
Intensifying screens is purposed to Correct Answers Amount of
radiation needed to make an exposure
Inverse square law Correct Answers Intensity of the beam is
inversely proportional to the square of the distance
kVp controls the Correct Answers Penetrating power of the
Xray beam; increase by 15 if xraying a wet cast. 10 if dry.
kVp Correct Answers Control the quality of the beam
Large focal spot Correct Answers Longer Xray tube life
