concentrated volume of contrast media?
a. bolus
b. infusion
c. extravasation
d. luminal ANS >>> a. bolus
Which of the following methods utilizes a detector that captures x-ray energy and
converts it into an electronic signal?
a. indirect capture
b. CCD
c. cassette-based radiography
d. direct capture ANS >>> d. direct capture
The energy of a characteristic x-ray photon created when an L shell electron fills a
K shell vacancy in a tungsten atom will have which of the following energies?
a. 69.5 keV
,b. 57.5 keV
c. 91.5 keV
d. 12 keV ANS >>> b. 57.5 keV
The energy of characteristic photons is determined by the difference in binding
energies between the two electron shells involved in the process, which in this
question are K and L shells. 69.5 (K shell) minus 12 (L shell) equals 57.5.

Exposure latitude is also known as which of the following?
a. dynamic range
b. spatial resolution
c. subject contrast
d. characteristic response ANS >>> a. dynamic range
