What is the range of the anode heel effect?

The anode heel effect refers to the phenomenon where the intensity of the X-ray beam is strongest towards the cathode end and gradually decreases towards the anode end. This effect is particularly pronounced in procedures using a fixed anode X-ray tube.

In the context of the range of the anode heel effect, the angle of the anode can influence how pronounced this effect will be. Typically, the anode heel effect can be observed with an anode angle generally between 7 to 15 degrees. This range allows for a sufficient difference in radiation intensity coming from the two different sides of the X-ray beam, providing the necessary gradient that is characteristic of the effect.

While one may consider wider angles, such as those presented in the other choices, they would not accurately represent the typical range for the anode heel effect. Understanding the correct range helps radiologic technologists set up their imaging procedures correctly to account for this effect, ensuring optimal image quality.
