| 摘 要： | 生物组织散射元平均间距是描述生物组织微观结构和超声散射特性的重要参数。文中构造了生物组织散射元一维超声散射模型，提出用Ｗｉｇｎｅｒ－Ｖｉｌｅ分布函数方法估计生物组织散射元平均间距，仿真结果表明这一方法具有良好的空间分辨率，能检测出生物组织散射元平均间距细微的非均匀性变化，且有良好的抗噪声性等一系列优良特性

| Abstract: | Average scatterer spacing is one of the important parameters in describing the biological tissue microstructure and its ultrasonic scattering characteristics. The application of Wigner-Ville distribution methods to measure the average scatterer spacing of biological tissue is demonstrated in this paper. The simulation results indicate that this method has such advantages as high spatial resolution, sensitive to the subtle variation in spatial distribution of scatterer, even in noise background. |
