update} 164 QUESTIONS AND ANSWERS
100% CORRECT
Motion - correct answer the length of the exposure time (s) for a radiograph, is used to
primarily control
400 ma,0.110 sec, 80 kvp - correct answer a radiograph is taken 400 ma, 55 ms, 95 kvp.
A second image could be taken to improve contrast at
Attenuation - correct answer when an xr photon passes through matter, it undergoes
a process called
Reduce in number - correct answer during the process of attenuation, xr photons in
the beam
,Lead (z=82) - correct answer in which element are the inner-shell electrons more
tightly bound to the nucleus?
Increase; decrease - correct answer as the electron shells move farther from the
nucleus, total electron energies_ and binding energies_.
Scatter - correct answer when xr photons interacts w/matter & change direction, the
process is called
Exists w/less energy - correct answer if a photon interacts w/matte & scatter, the
photon
Inner - correct answer during photoelectric absorption, a/an_ shell electron is ejected
, Photoelectron - correct answer during photoelectric absorption, the ejected electron is
called a/an
Photon is released - correct answer when an electron from an outer shell fills a
vacancy in an inner shell
A characteristic photon - correct answer during the photoelectric interaction, as an
electron transfer from an outer shell to a vacant inner shell energy is released in the
form of
Barium - correct answer secondary radiation energies are highest for which element
Loosely bound outer-shell - correct answer compton scattering occurs when an
incident xr photon interacts w/a_ electron
