CAMRT Radiography Practice Exam

What is the advantage of slip ring technology in CT?

1. Improves image quality by reducing motion artifacts

2. Eliminates the need for contrast media

3. Allows for continuous rotation of the x-ray tube

4. Reduces radiation dose to the patient

The correct answer is: Allows for continuous rotation of the x-ray tube

The advantage of slip ring technology in computed tomography (CT) is that it allows for continuous rotation of the x-ray tube. This continuous motion enables faster data acquisition and improved scanning efficiency, which is crucial for producing high-quality images in a shorter amount of time. As the x-ray tube rotates smoothly around the patient without the need to stop and reposition, it enhances the ability to acquire data for helical or spiral CT scans. This technique leads to better accuracy in imaging, reduces beam overlap, and improves the overall quality of the images obtained. Additionally, it allows for advanced imaging techniques, like multi-detector CT, that contribute to the detailed visualization of structures within the body. Meanwhile, the other options, while they describe certain benefits that can be associated with various imaging technologies, do not accurately represent the primary advantage offered specifically by slip ring technology.
