Question

Quizplus · Accepted Answer

When patient SID or SOD increases, the patient ESE decreases. This is because the X-rays spread out over a larger area as the distance between the source of the X-rays and the patient increases, resulting in a decrease in the intensity of the X-rays. Therefore, the ESE decreases with an increase in distance.
