Quizplus · Accepted Answer

The anode-heel effect occurs due to the variation in the intensity of the X-rays emitted by the anode of the X-ray tube. The intensity is greater on the cathode side and decreases towards the anode end. Placing the cathode over the base (lower end) of the area being imaged would ensure that the thicker and denser part of the anatomy is being irradiated by the stronger and more penetrative X-ray beam. This leads to a more uniform and diagnostic image. On the other hand, placing the cathode over the apex (upper end) may result in an underexposed and uninterpretable image. Therefore, option B is the best choice.
