Quality Assurance (QA)
According to professional standards (Clinical Ultrasound in Gynecology and Obstetrics, 2026), the quality system includes: quality control (QA), quality metrics, quality maintenance, standardized classification, reporting templates, storage and review of images, recertification, and structured feedback. Specific numerical QA thresholds are not provided in the fragments [to be clarified].
