In a QA program, which task should be performed every three months?

• A. checking water filters
• B. film retake analysis
• C. checking film developer temperature
• D. grid uniformity and alignment

Answer: (B)

In a QA program, you monitor image quality and system performance over time to catch trends that could affect patient dose or diagnostic value. Film retake analysis fits this purpose well because it collects data on why repeats occur—from technique issues to processing or equipment factors—and turns those findings into actionable improvements. When you review retakes every three months, you gain enough data points to spot patterns and shifts, then adjust technique charts, exposure protocols, or processing steps accordingly. This cadence balances having meaningful trend information with not overloading staff with constant review.

Other tasks tend to require different cadences. Checking water filters is ongoing maintenance that’s done as part of regular facility upkeep. Checking film developer temperature is a daily control to ensure consistent processing. Grid uniformity and alignment are typically addressed when a grid is installed or after service, or on a less frequent basis, rather than on a fixed three-month schedule.
