Three-dimensional ultrasound is a new modality finding its way into clinical practice. Most of the major ultrasound vendors are now developing three-dimensional ultrasound capabilities. We expect that although three-dimensional ultrasound will not replace two-dimensional ultrasound, many additional benefits will be identified and its use will continue to grow. The ability to evaluate anatomy and pathology with multiplanar and surface-rendered images provides physicians additional valuable clinical information. Volume data allows for a specific point in space to be evaluated from many different orienta tions by rotating, slicing, and referencing the slice to other orthogonal slices. It also allows for new volume-rendering displays that show depth, curvature, and surface images not available with conventional methods. The current limitations of image resolution, intuitive interfaces for obtaining and displaying optimal images, and technologic limitations for data storage and manipulation (including real-time three-dimensional ultrasound) will surely be overcome in the near future.
三维超声是一种正逐渐进入临床实践的新方法。大多数主要的超声设备供应商目前都在开发三维超声功能。我们预计，尽管三维超声不会取代二维超声，但将会发现许多额外的益处，并且其应用将持续增长。利用多平面和表面渲染图像评估解剖结构和病理状况的能力为医生提供了额外的有价值的临床信息。容积数据允许通过旋转、切片以及将切片与其他正交切片进行参照，从许多不同方向评估空间中的特定点。它还允许进行新的容积渲染显示，呈现出传统方法无法获得的深度、曲率和表面图像。图像分辨率、获取和显示最佳图像的直观界面以及数据存储和处理（包括实时三维超声）方面的技术限制，在不久的将来肯定会被克服。
