提出了超声造影剂体外声学特性的标准化程序,保留了一个特别重要的新声学参数:这是星星,散射衰减比,用于量化造影剂的有效性。星星表示造影剂增强包含造影剂的组织的可视化的能力,同时,因此,期望生产具有高星星的造影剂,该造影剂具有良好的散射性质以改善图像可视化,并且具有低衰减以使下面的生物结构成像并避免阴影。在这项研究中,我们提出的方法计算和测量的星星和比较不同的造影剂。(C)1998年世界医学和生物学超声联合会。
A standardization procedure for bl vitro acoustic characterization of ultrasound contrast agents is presented, One new acoustic parameter for particular importance is retained: This is STAR, scattering-to-attenuation ratio, for quantification of the effectiveness of the contrast agent, The STAR expresses the ability of the contrast agent to enhance the visualization of the tissue containing the contrast agent and, at the same time, represents the degree of its absorption, So, it is desirable to produce a contrast agent with high STAR, having good scattering properties to improve the image visualization, and low attenuation to image the underlying biological structures and to avoid shadowing. In this study, we present methods for calculations and measurements of the STAR and comparison between different contrast agents. (C) 1998 World Federation for Ultrasound in Medicine & Biology.
