An important part of any QA program, to be done every THREE MONTHS, is: 1) checking water filters 2) checking film developer temperature 3) film retake analysis 4) grid uniformity and alignment

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

Answer: (A)

Focusing on a quality assurance program, tracking imaging outcomes over a three-month period provides a meaningful snapshot of procedure quality and operator performance. Film retake analysis captures how often exams must be repeated due to technique, positioning, exposure errors, or processing issues. By reviewing these retakes quarterly, you can calculate a retake rate, identify common causes, and implement targeted improvements—such as updated positioning protocols, additional training, or process tweaks—to reduce repeats and patient dose over time. This metric directly reflects image quality and workflow, making it well suited to a quarterly review.

Water filter checks, while important, are maintenance items with more frequent or specified replacement schedules and are not typically the quarterly QA focus. Checking film developer temperature is a daily quality control parameter to ensure processing consistency. Grid uniformity and alignment are validated during installation or after grid service and are not routine quarterly checks.
