Which of the following cannot reduce patient exposure and
operator exposure:
a. Restricting the x-ray beam "on" time to a minimum
b. Using the lowest mA and highest kVp
c. Restricting the x-ray beam to the smallest size
d. Keeping patient-screen distance to a maximum - ANSWER-d.
Keeping patient-screen distance to a maximum
A photocell located between the image intensifier and the
television camera
system that is designed to maintain a range of
brightness is a:
a.
Photoemitter
b. Vidicon
c. Automatic brightness
stabilizer
d. None of the above - ANSWER-c. Automatic
brightness stabilizer
,In order to maintain image clarity, the path of electron
flow from the
photocathode to the output phosphor is
controlled by:
a. Accelerating
anode
b. Electrostatic
lens
c. The vaccum glass
tube
d. Input phosphor - ANSWER-b.
Electrostatic lens
The image intensifier input phosphor differs from the output
phosphor in that the
input
phosphor:
a. Is much larger than the output
b. Emits electrons, and the output phosphor emits light photons
c. Absorbs electrons, and the output phosphor absorbs light
photons
d. Are fixed sizes, and the output phosphor size can vary -
ANSWER-a. Is much larger than the output
,The total brightness gain of an image intensifier is a result of
(1) flux gain, (2)
minification ratio, (3)
focusing gain:
a. 1
b. 2
c. 1 and
2
d. 1 and 3 - ANSWER-c. 1
and 2
The electronic image, which is produced at the input side
of a television
camera, is canned by means
of a/an:
a. Photo beam
b. Proton gun
c. Electron gun
d. Photocathode - ANSWER-c. Electron gun
An electron gun (also called electron emitter) is an electrical
component in some vacuum tubes that produces a narrow,
collimated electron beam that has a precise kinetic energy. The
largest use is in cathode ray tubes (CRTs), used in nearly all
television sets, computer displays and oscilloscopes that are
not flat-panel displays.
, Each frame of a television picture consists of:
a. 262 scanning lines
b. 525 scanning lines
c. 1050 scanning lines
d. 2200 scanning lines - ANSWER-b. 525 scanning lines
The input screen of a television camera tube converts the light
image from the
image intensifier into
a/an:
a. X-ray image
b. Electronic image
c. Visible image
d. None of the above - ANSWER-b. Electronic image
The electronic signal, which carries the information from the
television camera
to the monitor is
termed:
a. Synchronization
pulse
b.
Bandpass
c. Return
beam
