What is the result if the total lead content of a grid is
decreased?
a. Decreased scatter absorption.
b. Greater image contrast.
c. Higher patient dose.
d. Increased scatter absorption - Answer-a. Decreased
scatter absorption.

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. - Answer-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). - Answer-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. - Answer-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. - Answer-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 - Answer-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. - Answer-b. Tracking
radiology scheduling information.
