Which anode angle with the same size actual focal spot can tolerate the highest technical settings without overheating?

The correct choice, representing the anode angle that can tolerate the highest technical settings without overheating, is typically the largest angle listed, which is 22 degrees.

A larger anode angle allows for a wider effective focal spot area while maintaining the same size actual focal spot, which distributes the heat generated during exposure over a larger surface area. This greater heat dispersion capability reduces the risk of overheating the anode during high-power exposures.

As the angle of the anode decreases, the effective focal spot becomes narrower, concentrating the heat on a smaller area, thus making it more susceptible to overheating under higher technical settings.

Therefore, a 22-degree anode angle is better suited for handling higher mA settings and shorter exposure times because it can effectively manage thermal load, improving the overall efficiency and longevity of the radiographic equipment in high-demand situations.
