Ultrasound has become less expensive, easier to use, and more portable over the last decade. These changes have made it more useful in the perioperative environment for a variety of diagnostic and procedural purposes. Understanding the principles and physics behind ultrasound and becoming aware of some of the pitfalls of its use are critical to effective utilization of this technology.
