摘要

组织模拟在声辐射力脉冲成像技术的发展中起着至关重要的作用。本文研究了琼脂基组织模拟模型的制备与研究。研究了不同浓度琼脂样品(重量比为1.7%-10%)的声学和弹性性能。声学特性测量采用脉冲回波发射接收原理。采用压缩试验对试样的杨氏模量进行了测定。可复制的假体制备程序是标准化的，用于匹配正常和异常人体软组织的各种特性。

Characterization of tissue mimicking phantoms for acoustic radiation force impulse imaging

Tissue mimicking phantoms play a crucial role in the development of Acoustic Radiation Force Impulse Imaging. This paper deals with the preparation and study of agar based tissue mimicking phantoms. Acoustic and elastic properties are studied for various concentration of agar samples (1.7%-10% by weight). Acoustic properties are measured using pulse echo transmit receive principle. Young's modulus of the samples are measured using compression test. Reproducible phantom preparation procedures are standardised for matching various properties of normal and abnormal human soft tissues.
