Integrating these tests into your regular workflow creates a strong foundation for a successful quality control program. From using phantoms to check for artifacts to performing simple visual checks, each step plays a vital role in delivering accurate and reliable diagnostic images.
Test Phantoms and Detect Artifacts
One of the most important weekly tests involves using a phantom to evaluate your system’s performance. The ACR’s Digital Mammography Phantom is designed to cover most of the detector area, making it easier to spot artifacts across the entire image. This phantom contains objects that mimic breast tissue, including fibers, specks, and masses, allowing you to confirm that your system can clearly visualize these small but critical details. Regularly performing this test helps ensure your medical imaging equipment is performing optimally and that you can consistently produce high-quality, diagnostically valuable images. It’s a fundamental check for any mammography service.
Check Compression Force and Thickness Indicators
As part of your monthly QC, you’ll need to verify the accuracy of your machine’s compression force and thickness indicators. The manual introduces a straightforward test to confirm that the compression thickness reading is accurate within 5mm. You can perform this check using a simple, consistent object, like two rolls of medical tape. Accurate compression is key for achieving uniform breast thickness during an exam, which leads to better image quality and is more comfortable for the patient. This simple test ensures the data your machine provides is reliable, contributing to both patient safety and diagnostic precision.
Perform Workstation QC and Visual Checks
Your quality control process extends beyond the mammography unit itself. Monthly QC also includes checks for the monitors where images are viewed, both at the acquisition workstation and the radiologist’s review station. This ensures that image quality is consistent from the moment of capture to the final diagnosis. The manual also provides a visual checklist for inspecting the general condition of the mammography machine. This quick visual scan helps you identify any obvious issues like loose parts or frayed cables that could pose a safety risk or affect equipment performance, making it an easy yet important part of your routine.
Conduct Facility QC Reviews and Annual Surveys
Quality control is a team effort. The ACR manual introduces a Facility QC Review, which requires the lead technologist, manager, and lead radiologist to meet and go over QC records together. This collaborative review helps identify trends, address ongoing issues, and ensure everyone is on the same page. In addition to these internal checks, a medical physicist must conduct an annual survey of all mammography equipment. This comprehensive evaluation is a cornerstone of the ACR’s accreditation program and provides an expert, third-party assessment of your equipment’s performance and safety, ensuring you meet all necessary standards.
How Mammography Phantoms Support Quality Control
Mammography phantoms are essential tools for any quality assurance program. Think of them as a consistent, reliable stand-in for breast tissue.

When you follow the QC manual, the phantom is what you’ll use to verify that your system is operating correctly, ensuring it can produce clear, accurate images for every patient. This process is fundamental to maintaining high standards in medical imaging.
One of the most important jobs for a phantom is helping you find artifacts. These are unwanted marks, smudges, or distortions on an image that could obscure important details or be mistaken for an abnormality. The latest ACR Digital Mammography Phantom, for example, is larger and designed to cover most of the detector area. This design makes it much easier to scan the entire image for artifacts that might otherwise go unnoticed, which is a significant step forward in preventing image quality issues before they impact patient care.
Beyond just finding artifacts, mammography phantoms contain tiny, embedded objects that simulate real-world clinical findings. These include fibers, specks that mimic microcalcifications, and masses. When you image the phantom, the goal is to see if your system can clearly resolve these objects. If they appear sharp and distinct, it’s a good sign that your equipment is sensitive enough to detect subtle abnormalities in actual breast tissue. This test provides direct feedback on the diagnostic quality of your images, confirming your system is performing as expected.
Using a phantom for regular testing creates a stable baseline for your equipment’s performance. By comparing images of the same phantom over weeks, months, and years, you can track any changes or degradation in image quality. This allows your team and medical physicist to identify and address problems proactively. This consistent, data-driven approach is the backbone of an effective QC program and is essential for complying with both ACR guidelines and federal regulations.

A clear and consistent system for record-keeping not only satisfies regulatory requirements but also strengthens your entire quality assurance program.
Which Records to Keep and for How Long
Understanding retention schedules is key to maintaining compliance with mammography quality control. The FDA has specific timelines based on how often you perform a test. For daily QC, you need to keep records for the previous 30 days. For weekly QC, that extends to the previous 12 weeks.
For tests performed monthly, quarterly, or semi-annually, the rule is a bit different. You must keep these records until your next annual inspection confirms compliance, or until the test has been performed two more times, whichever period is longer. While the FDA doesn’t mandate keeping annual QC images, the American College of Radiology (ACR) strongly recommends saving images from any test failures. This practice can be incredibly helpful for troubleshooting down the line.
How to Document Test Failures and Corrections
When a test fails, your documentation becomes your roadmap for fixing the issue. The ACR advises facilities to keep images of any test failures to help pinpoint the root cause of a problem. This visual evidence is invaluable for your medical physicist and service engineers.
To streamline this process, the ACR introduced a Corrective Action Log in its updated manual. This log provides a structured way to track any issues you identify during QC testing, from the initial failure to the final resolution. Using this tool ensures that nothing falls through the cracks and creates a clear, auditable trail of your corrective actions, which is essential for both compliance and continuous quality improvement.
