The anode heel effect in X-ray imaging results in:

• A Complete absorption of the beam at the anode edge
• B Increased beam intensity on the anode side of the field
• C Uniform beam intensity across the entire field
• D Increased beam intensity on the cathode side of the field ✓

Explanation

The anode heel effect causes X-ray intensity to be higher on the cathode side and lower on the anode side due to self-absorption of X-rays by the anode target at steep angles. This effect is utilized clinically by positioning thicker body parts under the cathode side for better penetration.
