A chest x-ray calls for 100 kVp kVp, 9 mAs, which results in an x-ray intensity of 359 μGy measured at the patient's location. If the mAs is increased to 17 mAs, what will the new x-ray intensity be? Give your answer to the nearest μGy
Homework Answers
(intensity is directly proportional to current squared)
k is Constant and I is the current
Intensity2 = 1281μGy
