LRA 222: Written Examination Paper
1.SID is not a primary exposure technique factor: mAs and kVP are
2.The Grid is the device used to absorb in the radiation
leaving the patient before it reaches the .: scatter radiation and
image receptor.
3.If the SID is increased, the beam intensity and radiation reaching the IR is
.: decreased
4.To maintain the original exposure to the IR,: mAs must be increased
5.With digital imaging,: overexposure will result in an image with
appropriate brightness because the computer will make the required
adjustments.
6.Higher kVp results in absorption and variation in
the intensities exiting the patient.: less and less.
7.the mAs does not have a direct effect on . During
computer processing, image brightness is maintained when the is too
low or too hight (within reason).: image brightness, mAs
8.Low kVp produces subject contrast, and high kvp produces
subject contrast.: hight and low
9.Less scatter radiation reaching the IR results in .:
High- er radiographic contrast
10.To minimize radiation exposure, the beam should be as
much as possible, the grid used only when , and use the
amount of to produce a diagnostic image.: restricted, needed,
least, mAs.
11.the grid is placed between the and the .: body part and IR
