What does stability in a CT unit refer to?

Stability in a CT unit primarily refers to the lack of need for frequent calibration. A stable CT unit maintains consistent imaging quality and performance over time without requiring regular adjustments or recalibrations. This consistency is critical for ensuring reliable diagnostic results, as frequent calibrations can lead to variability in images that may affect diagnostic accuracy.

While operational performance, resilience under extreme conditions, and the ability to withstand physical stress are important factors in assessing overall equipment functionality, they do not specifically define stability. Stability focuses on how consistently the CT unit operates within its specified parameters without needing recalibrations, which is essential for routine clinical use.
