What is the intended use of "test phantoms" in radiographic quality control?

Test phantoms are specifically designed to simulate patient anatomy for testing the performance of imaging systems. They provide a standardized method of assessing various aspects of radiographic quality, including resolution, contrast, and overall image quality. By using test phantoms, technicians and radiologists can replicate typical patient conditions without the need for actual patients, allowing for consistent and repeatable tests.

This enables practitioners to evaluate how well the imaging system performs under controlled conditions, which is crucial for maintaining high standards in radiographic imaging. Test phantoms can mimic different tissue types and structures, thus providing relevant data on how effectively the imaging equipment captures these variations. Regular testing with phantoms helps ensure compliance with safety standards and regulatory requirements, ultimately contributing to accurate diagnoses and optimal patient care.
