Abstract

Ultrasound imaging of flow has seen a tremendous development over the last sixty years from 1-D spectral displays to color flow mapping and the latest Vector Flow Imaging (VFI). The paper gives an overview of the development from current commercial vector flow systems to the latest advances in fast 4-D volumetric visualizations. It includes a description of the radical break with the current sequential data acquisition by the introduction of synthetic aperture imaging, where the whole region of interest is insonified using either spherical or plane waves also known as ultrafast imaging. This makes it possible to track flow continuously in all directions at frame rates of thousands of images per second. The latest research translates this to full volumetric imaging by employing matrix arrays and row-column arrays for full 3-D vector velocity estimation at all spatial points visualized at very high volume rates (4-D).

流量估计技术的历史和最新进展:从二维的一维到四维的三维

在过去的60年里，超声成像技术从一维光谱显示到彩色流成像再到最新的矢量流成像(VFI)，取得了巨大的发展。本文概述了从目前的商业矢量流系统到快速四维体可视化的最新进展。它包括一个描述根本突破与目前的顺序数据采集引入合成孔径成像，其中整个感兴趣的区域是使用球面或平面波，也称为超快成像。这使得以每秒数千张图像的帧率在所有方向上连续跟踪流成为可能。最新的研究将其转化为全体积成像，通过使用矩阵阵列和行列阵列在所有空间点上以非常高的体积速率(4-D)进行全三维矢量速度估计。
