Question

multiple choice 1 point
for an x - ray beam operated at 90 kvp, the required minimum filtration must be
0.7 mm al/eq inherent plus 1.0 mm al/eq added.
1.0 mm al/eq inherent plus 1.5 mm al/eq added.
0.5 mm al/eq inherent plus 1.0 mm al/eq added.
none of the above.
multiple choice 1 point
a compensating wedge filter would be appropriate for
pa hand radiography.
ap shoulder radiography.
ap foot radiography.
ap cervical spine radiography.

Explanation:

For the first question, the required minimum filtration for an x - ray beam operated at 90 kVp is 1.0 mm Al/Eq inherent plus 1.5 mm Al/Eq added. For the second question, a compensating wedge filter is appropriate for AP foot radiography as the foot has varying thicknesses and the wedge filter can help to even out the exposure.

Answer:

1. B. 1.0 mm Al/Eq inherent plus 1.5 mm Al/Eq added
2. C. AP foot radiography
