There are two kinds of the acoustic microscope, the one is the Scanning Laser Acoustic Microscope, SLAM and the other the Mechanical Scanned Acoustic Microscope, SAM. In the acoustic microscope, high frequency ultrasound of 100 MHZ to 500 MHZ was used and the resolving power was in the range of 5 to 10 microns. The propagating speed and attenuation of ultrasound from the C-mode image which was obtained by mechanically scan with laser or ultrasound. From the results of the experiments by using the SAM to analyze acoustic characteristics of the tissue specimens which were taken from the patients with cardiac sarcoidosis, HCM, DCM, gastric and kidney cancer, clinical significances and usefulness of the evaluation for physical characteristics of the tissue were discussed in this paper.
声学显微镜有两种，一种是扫描激光声学显微镜（SLAM），另一种是机械扫描声学显微镜（SAM）。在声学显微镜中，使用了100兆赫兹至500兆赫兹的高频超声，分辨率在5至10微米范围内。通过激光或超声进行机械扫描获得的C模式图像中的超声传播速度和衰减情况。本文通过使用SAM对取自心脏结节病、肥厚型心肌病（HCM）、扩张型心肌病（DCM）、胃癌和肾癌患者的组织标本的声学特性进行分析的实验结果，探讨了对组织物理特性评估的临床意义和实用性。
