声学血管造影是一种对比增强超声技术，它依赖于超谐波成像来形成微血管的高分辨率三维图。为了获得组织和对比剂之间的信号分离，声学血管造影术已经用具有不重叠带宽的双频换能器进行。这实现了高对比度-组织比，并且高频接收元件的选择提供了高分辨率。在这一章中，我们描述了声学血管造影术背后的技术以及这种对比度增强微血管成像技术的逐步实现。
Acoustic angiography is a contrast-enhanced ultrasound technique that relies on superharmonic imaging to form high-resolution, three-dimensional maps of the microvasculature. In order to obtain signal separation between tissue and contrast, acoustic angiography has been performed with dual-frequency transducers with nonoverlapping bandwidths. This enables a high contrast-to-tissue ratio, and the choice of a high frequency receiving element provides high resolution. In this chapter, we describe the technology behind acoustic angiography as well as the step-by-step implementation of this contrast enhanced microvascular imaging technique.
