What results from the continuous feed of the bed in helical CT?

The continuous feed of the bed in helical CT, also known as spiral CT, leads to reduced scanning time. This continuous movement allows for the acquisition of data in a more efficient manner, enabling the CT scanner to capture a full volume of data in a shorter period compared to traditional sequential scanning methods. As the patient moves through the gantry, the x-ray tube rotates around them while simultaneously moving along the z-axis, which means that the entire volume of interest can be imaged rapidly. This efficiency not only enhances workflow but also reduces the time that a patient must remain still during the procedure, which is particularly beneficial in minimizing motion-related artifacts.

The increased speed of acquisition can contribute to improved patient comfort and throughput in clinical settings. Thus, the main advantage of this technology is its ability to produce images quickly while maintaining quality.
