Question

If a radiograph were made of an average-size knee using automatic exposure control (AEC) and all three photocells were selected, the resulting radiograph would demonstrate

insufficient density

Answer 1

When using automatic exposure control (AEC) on a radiograph of an average-size knee, if all three photocells were selected, the resulting radiograph would demonstrate insufficient density. The density of a radiograph refers to how dark or light the image appears.

Step-by-step explanation:

When using automatic exposure control (AEC) on a radiograph of an average-size knee, if all three photocells were selected, the resulting radiograph would demonstrate insufficient density. The density of a radiograph refers to how dark or light the image appears. Insufficient density means that the image would appear too light, making it difficult to discern any details. In this case, selecting all three photocells would result in the AEC system underexposing the image, meaning that not enough x-rays would be transmitted through the knee to create a properly exposed radiograph.
