Question

13 multiple choice 1 point if the mas of a radiograph is increased from 10 to 20, the result will be an increase in the ei number from 125 to 250. no change in the ei number. an increase in the ei number from 125 to 135. a decrease in patient exposure. 14 multiple choice 1 point the relationship between mas and exposure is exponential. directly proportional. indirectly proportional a squared relationship.

Explanation:

1. The Exposure - Index (EI) is directly proportional to the mAs (milliampere - seconds) in radiography. When mAs doubles from 10 to 20, the EI number also doubles if initially at 125, it will go to 250.
2. The relationship between mAs and exposure in radiography is directly proportional. As mAs increases, the amount of radiation exposure to the image receptor (and patient) increases linearly.

Answer:

1. an increase in the EI number from 125 to 250.
2. directly proportional
