Higher _______ produces more energetic photons, is more penetrating, and produces more
grays on a radiographic image, lengthening the scale of contrasts.
,A.kilovoltage

one of the biggest advantages of CR/DR is the _______ it offers
a. latitude
b. longitude
c. Silver bromide crystals
d. Rare earth phosphor
a. latitude
also known as exposure latitude
Shepherd page 332
, With CR/DR this affords a much greater exposure latitude and technical inaccuracies can be
effectively eliminated. Over exposures of up to _______ percent and under exposures of up to
_____ PERCENT are reported as recoverable thus eliminating most retakes
A.
B.
C.50/50
D.
A. percent
Shepherd page 332
in CR/DR there is a _______ relationship between the exposure given to the PSP and its
resulting luminescence as it is scanned by the laser
A.sigmoidal
B.nonlinear
C.linear
D.circular
C.linear
