The anode heel effect is the gradual reduction of radiation intensity along the anode end of the x-ray beam. This occurs due to the angle of the anode target and the fact that more radiation is absorbed as it passes through a greater amount of material. The shorter the SID (source-to-image distance) and the larger the field size, the more pronounced the heel effect will be. Using low kVp techniques may affect the overall intensity of the beam, but it does not significantly affect the anode heel effect.
