Which QA/QC guidelines should be checked daily?

• A. 1, 2, and 3
• B. 1 and 2
• C. 1 and 3
• D. 2 and 3

Answer: (B)

Daily QA/QC focuses on quick, repeatable checks that ensure the system is ready for use and that patient dose and image quality stay consistent from day to day. The two items kept for daily checks are the ones you can perform at the start of each day with minimal setup and that address the most immediate concerns: the imaging system’s output matches the selected technique and stays reproducible across exposures, and the exposure controls respond consistently when technique factors are adjusted. These checks directly affect dose accuracy and diagnostic quality in every exam, so they’re prioritized for daily verification.

The third item, while important, usually requires more time, a phantom, or a more in-depth measurement, so it’s typically done less frequently (weekly or monthly) rather than every day. This separation keeps daily checks practical while still ensuring comprehensive performance over time.
