What test pattern is used to ensure that acquisition workstation monitors are free of dust and artifacts?

The Society of Motion Picture and Television Engineers (SMPTE) test pattern is specifically designed to evaluate the performance of monitors, including checking for dust and artifacts. This pattern consists of a series of grayscale gradients, geometric shapes, and resolution targets that help in identifying and evaluating any visual issues, such as pixel malfunction or excessive dust on the screen.

Using the SMPTE test pattern in a clinical setting ensures that the images displayed on acquisition workstation monitors are clear and accurate, which is crucial for the diagnosis and treatment planning in mammography. Regularly utilizing this test pattern is a standard practice to maintain quality control and ensure that the monitors are functioning correctly without interference from artifacts that could potentially affect patient care.

Other organizations, such as the NEMA, ACR, and IEC, focus on different aspects of imaging technology and standards rather than the specific evaluation of monitor quality with a test pattern.
