摘要-组织定征的一个重要超声传播特性是声速。扫描激光声学显微镜(SLAM)提供了在亚毫米尺度上确定组织样本或样本部分中声速的能力。这种能力潜在地可以用于开发量化组织声速的空间梯度的指数。已经开发了用于使用SLAM确定声速的自动化技术。现在可以从声速分布的SLAM测量定量研究组织异质性的程度。不
Abstmct-An important ultrasonic propagation property for tissue characterization is the speed of sound. The scanning laser acoustic microscope (SLAM) provides the capacity to determine the speed of sound in tissue specimens or portions of specimens on the submillimeter scale. This capability potentially can be utilized to develop indices that quantify the spatial gradient of the tissue’s speed of sound. An automated technique for determining the speed of sound using the SLAM has been developed. It is now possible to study quantitatively the degree of tissue heterogeneity from SLAM measurements of the speed of sound distribution. T
