在透射模式SAM中，待检查的生物组织切片通常安装在聚酯膜保持器上以构成双层样本。本文研究了由固定保持器和组织切片组成的双层结构的一维声学模型，定量地讨论了声在组织切片中的传播特性。基本上已经阐明，振幅图像中的亮度变化对应于声吸收中的亮度变化，并且相位图像中的亮度变化对应于组织切片中的声速中的亮度变化。
In transmission mode SAM, a biological tissue section to be examined is usually mounted on a polyester film holder to compose a double-layered specimen. In this paper, a one dimensional acoustic model for double layers composed of the mounting holder and a tissue section is investigated to discuss the propagation properties through the specimen quantitatively. It has been basically clarified that variations of brightness in the amplitude image correspond to those in acoustic absorption and that variations of brightness in the phase image correspond to those in sound speed in the tissue section.
