    AbstractThe use of ultrasonography in medical practice has evolved dramatically over the last few decades and will continue to improve as technological advances are incorporated into daily medical practice. Although ultrasound machine size and equipment have evolved, the basic principles and fundamental functions have remained essentially the same. This article reviews the general ultrasound apparatus design, the most common probe types available, and the system controls used to manipulate the images obtained. Becoming familiar with the machine and the controls used for image generation optimizes the scans being performed and enhances the use of ultrasound in patient care.Copyright © 2014 Elsevier Inc.
