What is the purpose of quality control (QC) tests on radiographic equipment?

• A. To ensure consistent image quality, safety, and adherence to standards.
• B. To increase patient throughput.
• C. To replace technologists.
• D. To reduce radiation exposure to zero.

Answer: (A)

Quality control tests on radiographic equipment ensure the system operates consistently, safely, and in line with established standards. By routinely checking aspects such as exposure accuracy (kVp, mA, timer), beam alignment and geometry, image receptor alignment, reproducibility of outputs, collimation, and safety interlocks, any drift or fault is detected early. This helps reduce repeated exams, keeps patient doses appropriate, and ensures images meet diagnostic requirements. QC supports dose optimization and regulatory compliance, not by aiming to eliminate radiography but by maintaining reliable performance so each image can be trusted. It isn’t about increasing throughput, replacing technologists, or reducing exposure to zero; those are not the goals of QC.
