Ultrasonics. Pulse-echo scanners. Simple methods for periodic testing to verify stability of an imaging system’s elementary performance Ingestion-build-202139 user verification1 Scope This document specifies requirements and methods for periodic testing of the quality of diagnostic medical ultrasound systems with linear array, curved linear array, single element, annular array, phased array, matrix linear array transducers and two dimensional arrays. Image interpretation and measurement workstations are included. Usually, periodic testing is referred to here as quality control. This document represents a minimum set of such
