The processor defaced an AP foot projection obtained at 50 kVp at 30 mAs. Before repeating the projection, the technologist noticed that the image was slightly overexposed at the area of inter-est.
It would not have been dark enough to cause it to need repeating. What new technique should the technologist use when she repeats the projection?
a. 48 kVp at 30 mAs
b. 50 kVp at 15 mAs
c. 50 kVp at 21 mAs
d. 42 kVp at 30 mAs
Question 2
An AP abdomen projection was obtained using 85 kVp at 10 mAs. The resulting image demon-strated excessively low contrast, although the density was acceptable.
What new technique could be used to obtain the projection with equal density but higher con-trast?
a. 72 kVp at 10 mAs
b. 72 kVp at 20 mAs
c. 81 kVp at 13 mAs
d. 98 kVp at 5 mAs
