What device may help provide an even density on a radiograph of an AP axial projection of the foot?

Question

Quizplus · Accepted Answer

A wedge compensating filter is designed to help compensate for differences in tissue density, making the radiograph appear more even. This would be the best choice for an AP axial projection of the foot. The lead shield is used to protect areas of the body from unnecessary radiation, the wedge positioning sponge helps to position the patient properly, and the sandbag is used for immobilization. None of these devices are specifically meant to provide an even density on a radiograph.
