question 15 / 40
how is the x - ray beam changed when milliamperage (ma) is increased by a factor of 2?
beam quality increases by a factor of 2
beam quality increases by a factor of 2²
beam quantity increases by a factor of 2
beam quantity increases by a factor of 2²

Explanation:

The milliamperage (mA) in x - ray production is directly related to the number of electrons flowing through the x - ray tube, which in turn affects the quantity of x - rays produced. When mA is increased by a factor of 2, the number of electrons striking the target increases by a factor of 2, leading to a proportional increase in the number of x - rays (beam quantity). Beam quality is related to kVp (kilovoltage peak) and not directly to mA.

Answer:

C. Beam quantity increases by a factor of 2
