空间复合成像是一种技术，其中从不同方向获得对象的多个共面断层超声图像，然后将其组合成单个复合图像。实时空间复合使用电子束转向从不同视角快速获取分量帧。以实时帧速率组合分量帧以产生具有减少的散斑和改善的镜面反射体连续性的复合图像。30多年前首次报道了实时空间复合，但直到最近才在商业超声系统上可用。本文描述了ATL HDI 5000系统上实时空间复合成像的技术性能特征，并考虑了这些特征在血管超声检查中的临床相关性。
Spatial compound imaging is a technique in which a number of co-planar, tomographic ultrasound images of an object are obtained from different directions, then combined into a single compound image. Real-time spatial compounding uses electronic beam steering to rapidly acquire component frames from different view angles. The component frames are combined at real-time frame rates to produce compound images with reduced speckle and improved continuity of specular reflectors. Real-time spatial compounding was first reported over 30 years ago, but it has only recently become available on commercial ultrasound systems. This paper describes the technical performance characteristics of real-time spatial compound imaging on the ATL HDI 5000 system, and considers the clinical relevance of these characteristics in vascular sonography.
