CAMRT Radiography Practice Exam

What is the main consequence of excessive rotor prep time on the x-ray tube?

1. Increased image clarity

2. Heat generation in the tube

3. Wear due to filament vaporization

4. Improved tube longevity

The correct answer is: Wear due to filament vaporization

The main consequence of excessive rotor prep time on the x-ray tube is the generation of heat within the tube. When the rotor is engaged for an extended period, it leads to increased electrical energy flowing through the filament, which heats it up more than usual. This prolonged heating can cause significant wear and tear on the tube, potentially resulting in filament vaporization. While wear from filament vaporization is a concern, the immediate effect of excessive rotor prep time is primarily related to heat generation. The increase in heat can lead to premature tube failure or damage, affirming the importance of keeping rotor prep times within designated limits to ensure optimal performance and longevity of the x-ray tube.
