During the past two decades, the development and maturation of ultrasonography as a diagnostic tool has revolutionized the practice of radiology, cardiology, obstetrics and surgery. In fact, few areas of medicine have not been affected by this technology. Unlike the still-frame images of standard X-rays and computerized axial tomography (CAT) scans, ultrasound technology displays an ongoing cross-sectional image of an anatomic area in "real time," which can then be stored and played back on videotape. This ability to quickly assess function, as well as anatomy, has become invaluable in the management of critically ill patients.
在过去二十年中，超声检查作为一种诊断工具的发展与成熟彻底改变了放射学、心脏病学、妇产科学和外科学的诊疗方式。事实上，医学领域几乎没有哪个方面未受到这项技术的影响。与标准X光和计算机断层扫描（CAT）的静态图像不同，超声技术能“实时”显示解剖区域的动态横断面图像，这些图像随后可存储在录像带上并进行回放。这种快速评估功能以及解剖结构的能力在危重症患者的管理中已变得至关重要。
