Question

which of the following statements describes the relationship between milliamperage (ma) and patient dose?
patient dose is directly proportional to the milliamperage (ma)
patient dose is inversely proportional to the milliamperage (ma)
patient dose is directly proportional to the square of the milliamperage (ma)
patient dose is inversely proportional to the square of the milliamperage (ma)

Explanation:

In imaging techniques like X - rays, as the milliamperage (mA) increases, the number of electrons hitting the target increases, resulting in more X - ray photons being produced. This leads to a higher patient dose. So, patient dose is directly proportional to the milliamperage.

Answer:

Patient dose is directly proportional to the milliamperage (mA)
