Radiologic Technology Supervisor And Operator Practice Exam

What purpose do standardized QC tests serve?

Detect slowly evolving functional X-ray and equipment abnormalities Permit corrective action before significant deterioration of image occurs Both of the above None of the above

Correct Answer:

Both of the above

Explanation:

Standardized QC tests monitor X-ray system performance over time, so gradual changes or developing faults are detected early. They can reveal slowly evolving functional abnormalities in components like the X-ray tube, timers, geometry, or the image receptor. Because the tests use defined procedures and tolerance limits, any drift beyond those limits prompts corrective action—such as recalibration or component replacement—before image quality deteriorates significantly. In this way, QC tests both catch gradual faults and enable proactive maintenance to keep image quality consistent and patient dose controlled.
