猪的出血性淋巴结组织的声散射系数比正常淋巴结组织的小，且随频率的变化而变化，背向散射技术是在高频段进行组织定征的有效手段。
The backscatter coefficient of hemorrhage lymphnode is smaller than that of normal lymphnode and changes with the frequency. The ultrasonic backscatter microscope technique is a useful device…
结果高频背向散射系数较声速、声衰减更能反映组织结构的变化，高频超声图像具有高的分辨率。
Results Compared with sound velocity and attenuation, the backscatter coefficient could reflect the structural change of biological tissue. The high frequency ul…
