What advantage does the high-speed rotation (10,000 rpm) of the anode provide?

The high-speed rotation of the anode at 10,000 rpm significantly enhances the ability of the anode to dissipate heat. When the anode rotates at such high speeds, the surface area that is exposed to the electron beam is continually changing. This effective rotation spreads the heat generated during X-ray production over a larger area of the anode.

As a result, the thermal energy is distributed more evenly, which prevents localized overheating. This heat dissipation is crucial in maintaining the integrity of the anode and preventing damage or melting from excessive temperatures. Additionally, better heat management allows the X-ray machine to operate at higher currents and voltages, which can in turn increase the efficiency of X-ray production and extend the lifespan of the anode.

While the other choices may relate to the performance of the X-ray machine, the most direct benefit of high-speed anode rotation is its ability to handle heat effectively, ensuring consistent and reliable image quality while minimizing the risk of damage to the system.
