Question

3 multiple choice 1 point milliampere - second (mas) directly affects all of the following except beam quantity. beam intensity. beam quality. x - ray output. 4 multiple choice 1 point the factors that directly affect x - ray quantity are ma. time (s). filtration. both a and b.

Explanation:

For question 3, mAs determines the number of electrons crossing the x - ray tube per second and thus affects beam quantity, intensity and x - ray output, but not beam quality which is mainly related to kVp. For question 4, x - ray quantity is directly related to the product of mA (milliamperage) and time (S), while filtration mainly affects beam quality by removing low - energy photons.

Answer:

1. beam quality
2. both a and b
