What is the goal of a quality assurance (QA) program in radiography?

• A. To maximize patient throughput
• B. To maintain equipment performance, image quality, and radiation safety
• C. To minimize maintenance costs
• D. To standardize procedures without safety considerations

Answer: (B)

Ensuring imaging is reliable, safe, and of diagnostic quality. A quality assurance program in radiography focuses on keeping equipment performing consistently so that every image meets the standards needed for accurate interpretation, while also protecting patients and staff from unnecessary radiation. This means regularly verifying that the x-ray output is accurate and reproducible, the beam quality and filtration are appropriate, and image receptors respond predictably so gray scales and detail remain consistent. It also means confirming that safety systems—such as beam collimation, shielding, and interlocks—are functioning properly. Routine checks, from daily exposure indicator accuracy to periodic tests of timer accuracy, exposure linearity, and full-system alignment, help catch drift or faults before they affect patient care. By maintaining these elements, the QA program reduces repeat examinations, supports optimized technique and dose management, and upholds ALARA principles. While QA can enhance efficiency and help control costs, its primary purpose is not to maximize throughput or to standardize procedures without considering safety; it is to ensure safe, high-quality imaging.
