Question

Quizplus · Accepted Answer

A small focal spot should be used in situations where fine detail demonstration is important or where extremities are being imaged. However, a larger focal spot is more appropriate when the milliamperage setting is above 300, as this reduces the risk of overheating the anode. The patient's ability to control motion is unrelated to the choice of focal spot size.
