Proper radiation practices to keep patient dose minimized, but still achieving diagnostic quality, would be:

decreased kVp and decreased mAs
increased kVp and decreased mAs
decreased kVp and increased mAs
increased kVp and increased mAs

Question 2

In reference to the image, what projection/position of the part is represented?

AP oblique ankle with 45 degree medial rotation
AP oblique ankle with 15-20 degree medial rotation
AP oblique ankle with 15-20 degree lateral rotation
AP ankle

Answer to Question 1

increased kVp and decreased mAs

Rationale: To keep patient dose in consideration, kVp should be selected that will adequately penetrate the part of interest, while mAs should remain as low as possible. Increasing the mAs factor can contribute most significantly to patient dose.

Answer to Question 2

AP oblique ankle with 15-20 degree medial rotation

Rationale: The image represents an AP oblique ankle with 15-20 degree medial rotation. The entire mortise joint is well visualized. The medial mortise and lateral mortise are open indicating proper rotation.
