If a radiographer wanted to double image density without doubling
the patient's dose, which action should be taken?
a. Double milliampere-seconds (mAs).
b. Increase kilovolts peak (kVp) by 15%.
c. Increase milliampere-seconds (mAs) by 15%.
d. Double kilovolts peak (kVp).
b. Increase kilovolts peak (kVp) by 15%.
,Digital radiography has the ability to produce 16,000 shades of gray.
What appropriate bit depth (dynamic range) does this represent?
a. 10 bit depth.
b. 16 bit depth.
c. 12 bit depth.
d. 14 bit depth.
d. 14 bit depth.
Pelvis routine calls for an anteroposterior (AP) with a
perpendicular central ray (CR), and an axial AP with a 40 degree
cephalic angle. Using a caliper measurement, the technique chart
yields a perfect set of exposure factors for the perpendicular AP.
How will the necessary exposure factors for the axial differ from
the perpendicular AP?
a. Same measurement, same technical factors.
b. Same measurement, but more bone, higher kilovolts peak
(kVp) and milliampere-seconds (mAs).
c. Smaller measurement, lower kilovolts peak (kVp) and
milliampere- seconds (mAs).
d. Greater measurement, higher kilovolts peak (kVp) and
milliampere- seconds (mAs).
d. Greater measurement, higher kilovolts peak (kVp) and
milliampere- seconds (mAs).
,If 7 milliampere-seconds (mAs) provides optimal density without a
grid, which mAs should be used with a 12:1 grid?
a. 28.
b. 35.
c. 42.
d. 21.
b. 35.
If all the bucky digital images from one radiographic room seem to
appear excessively noisy, what might the radiographer suspect?
a. The automatic exposure control (AEC) is set at an
inappropriate speed class.
b. There is a problem with the digital receptor.
c. The x-ray room may need recalibration.
d. It could be an anomaly and should continue to be monitored.
a. The automatic exposure control (AEC) is set at an
inappropriate speed class.
, Which term refers to unwanted fluctuations in the brightness of an
image?
a. Flux.
b. Interference.
c. Noise.
d. Static
c. Noise.
Which function are Radiology information system (RIS) networks
are capable of performing?
a. Processing laboratory reports.
b. Tracking radiology scheduling information.
c. Recording and retrieving diagnostic images.
d. Tracking billing information.
b. Tracking radiology scheduling information.
Which best describes anode heel effect?
a. A phenomenon where x-ray intensity is greater under the cathode.
b. A phenomenon where x-ray intensity is greater under the anode.
c. Absorption of part of the x-ray beam by the focusing cup.
d. Absorption of part of the x-ray beam by the target track.
a. A phenomenon where x-ray intensity is greater under the cathode.
