After completing a radiograph using 27 mAs at 90 kVp, the image demonstrates adequate overall density but an area that is underpenetrated.In order to produce an optimum image in terms of contrast and penetration, the repeat image should be taken at
A)27 mAs and 100 kVp.
B)54 mAs and 77 kVp.
C)13 mAs and 94 kVp.
D)27 mAs and 94 kVp.

Question

Quizplus · Accepted Answer

DIncreasing the kVp (while maintaining the same mAs in option A or adjusting it slightly as in option D) will improve penetration without significantly altering the overall density of the image. Options A and D both increase kVp, which is the primary factor affecting penetration. Option A increases kVp to 100, and option D increases it to 94, both of which would enhance penetration of the underpenetrated area. Option A maintains the original mAs, ensuring the density remains adequate, while option D slightly adjusts the kVp for a more nuanced approach to improving penetration with minimal impact on contrast.
