Which equipment must be included in a quality assurance program?

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

Answer: (D)

A QA program in radiology must routinely verify every part of the imaging chain that affects dose and image quality. The equipment used for QA should cover the components that determine exposure accuracy, geometric alignment, image receptor performance, and the processing or display chain. When all these types of equipment are included, you get a complete view of whether the system is delivering the intended dose consistently and producing reliable, diagnostic-quality images. If any one category is left out, problems can slip by unnoticed—exposure settings might be correct on paper, but the image receptor or processing system could still be degrading image quality or altering dose. Therefore, including all relevant equipment in the QA program ensures comprehensive monitoring and safer, more consistent radiographic results.
