volume of contrast media?
a. bolus
b. infusion
c. extravasation
d. luminal
Ans: a. bolus
2). 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
3). 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.
