Which of the following is an aim of quality assurance programmes for radiography?

• A. Improve image color
• B. Increase exposure
• C. Reduce repeats
• D. Eliminate errors

Answer: (C)

Quality assurance in radiography centers on keeping image quality high while keeping patient dose as low as reasonably achievable. A key practical aim is to reduce the number of repeat examinations by catching and correcting issues that would necessitate rescans—things like incorrect exposure factors, poor positioning, or equipment faults. Fewer repeats mean less radiation exposure for patients and smoother workflow for the department. While QA does involve monitoring and improving overall image quality and addressing errors, it isn’t about eliminating every error—some may still occur, but the goal is to minimize them and standardize procedures. Improving image color isn’t a typical QA target in radiography, since images are grayscale and color fidelity isn’t a standard quality measure. Increasing exposure would raise patient dose without improving safety or quality, so it goes against QA principles.
