Which test performed semiannually assesses compression force?

The compression force test is essential in mammography as it evaluates the force applied to the breast during imaging. This test is typically conducted semiannually to ensure that the compression mechanism of the mammography unit is functioning correctly and applying adequate pressure. Proper compression is crucial not only for improving image quality by reducing motion and enhancing the visibility of breast tissues but also for optimizing the dose of radiation received by the patient.

By measuring the compression force, this test helps to maintain the device's efficacy and safety standards, ensuring that the system provides high-quality images while minimizing discomfort to the patient. This routine assessment is a part of quality assurance protocols that facilities must follow to comply with regulatory standards and to provide optimal care.

In contrast, other options like the visual checklist, image receptor quality test, and repeat analysis focus on different aspects of mammography quality assurance. The visual checklist involves a review of the unit’s physical state, the image receptor quality test assesses the performance of the imaging system, and repeat analysis examines the rate of repeat images to identify potential issues in technique or equipment. However, none of these specifically measure the force applied during breast compression, which is why the compression force test is the correct choice.
