Segmenting the data acquisition process into smaller rotation angles can improve which aspect of CT image quality?

Segmenting the data acquisition process into smaller rotation angles enhances temporal resolution. Temporal resolution in CT refers to the ability to accurately capture dynamic processes occurring over time, which is critical in applications like cardiac imaging or other dynamic studies. By using smaller rotation angles, the system collects data more frequently, allowing it to better depict changes within the imaged structure over time. This faster acquisition potentially reduces motion artifacts, which can be important in regions where fast physiological processes are occurring.

The improvement in temporal resolution is particularly relevant when imaging moving structures or during rapid physiological changes, as it allows for more precise timing in data collection. Consequently, this enables clinicians to observe changes more accurately over short periods, resulting in better overall image quality for dynamic processes.
