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.

exam?
a. recumbent
LPO b.
supine
,c. recumbent
RPO
d. prone -ANS-d.
prone

Which position will emphasize the mucosal lining of the medial wall of the
descending colon during a
lower GI exam? -ANS-left lateral
decubitus

bone? -ANS-AP

following methods?
a. a cassette that is electronically
charged b.
