Where does the heel effect distribute more radiation intensity?

Explanation:
The beam isn’t uniform; the anode heel effect makes the side of the image receptor nearer the cathode receive more radiation. Photons aimed toward the anode side pass through more of the anode target and are attenuated more, while photons toward the cathode side have a shorter path through the anode material and are less attenuated. That reduced attenuation on the cathode side results in higher intensity there, so the cathode side of the image receptor gets more exposure.
