All of the following are within acceptable kVp accuracy variance for an exposure using 80 kVp EXCEPT
FOR ________ kVp.
-86
-84
-82
-76 - correct answers:86
The kVp variance is within + 5%. At 80 kVp, the variance is 4 kVp (80 x .05 = 4). Therefore, 76 kVp - 84
kVp is within acceptable limits. - correct answers:visceral
