Broadband scanning acoustic microscopy (SAM) has been used to investigate the mechanical properties of sections of tissue with a resolution of around 8 microns. The work reported here extends these results by reporting the frequency dependence of the attenuation coefficient from 100-500 MHz. A discussion of the theory of the measurements is presented. The scanning laser acoustic microscope (SLAM) is used to characterize similar tissue sections at 100 MHz. The data obtained with the two forms of acoustic microscopy are compared with results from the literature.
宽带扫描声学显微镜（SAM）已被用于研究组织切片的力学性能，分辨率约为8微米。本文报道的工作通过报告100 - 500兆赫范围内衰减系数的频率依赖性扩展了这些结果。文中还对测量理论进行了讨论。扫描激光声学显微镜（SLAM）用于在100兆赫频率下对类似的组织切片进行表征。将两种声学显微镜形式获得的数据与文献中的结果进行了比较。
