Abstract
The implications of a fractal model of medium structure for the angular dependence of the ultrasonic differential scattering cross section and for the frequency dependence of the total ultrasonic scattering cross section are explored. The results for the differential scattering cross section agree well with published experimental values for liver and those for the total scattering cross section are not inconsistent with the literature data.
摘要
探讨了介质结构的分形模型对超声微分散射截面角度依赖性以及总超声散射截面频率依赖性的影响。微分散射截面的结果与已发表的肝脏实验值吻合良好，总散射截面的结果与文献数据也不矛盾。
