The "heel effect" refers to the phenomenon in x-ray imaging where the intensity of the x-ray beam is greater on the cathode side of the tube. This occurs because the x-rays are more easily absorbed or scattered as they pass through the thicker part of the anode, resulting in a decrease in intensity towards the anode side.
