Which of the following is a quality control activity performed in a PACS environment?

• A. Display calibration checks
• B. Data integrity verification
• C. Image quality assessment
• D. All of the above

Answer: (D)

In a PACS environment, quality control covers the whole imaging workflow—from how images are displayed to how they are stored and how the images themselves look. Display calibration checks ensure the monitors used for interpretation render brightness, contrast, and grayscale accurately, so details aren’t missed due to a faulty display. Data integrity verification protects images and their accompanying data as they are acquired, stored, transmitted, and retrieved, catching any corruption or misrouting that could compromise a study. Image quality assessment involves routine review of the actual diagnostic images to detect issues like blur, noise, artifacts, or compression effects that could affect interpretation. Together, these activities address the different facets of reliability and accuracy in PACS, making all of them standard quality control practices.
