Final answer:
The Anode Heel Effect is used to compensate for the uneven distribution of x-ray intensity across the x-ray beam. By angling the x-ray tube, it helps achieve a more even distribution and reduce the risk of overexposure and underexposure.
Step-by-step explanation:
The purpose of the Anode Heel Effect in x-ray tubes is to compensate for the uneven distribution of x-ray intensity that occurs across the x-ray beam. It is caused by the angle at which the x-rays are emitted from the anode target. The intensity of the x-rays is higher on the cathode side and decreases towards the anode side.
By angling the x-ray tube, with the cathode side closer to the patient, the Anode Heel Effect can be used to achieve a more even distribution of x-ray intensity.
This compensation is important for obtaining consistent image quality and reducing the risk of overexposure on the anode side and underexposure on the cathode side.
