超声波弹性成像技术在过去 10 年中得到了发展，成为对软生物组织的弹性特性进行成像的强大方法。该方法包括对感兴趣区域施加小的外部准静态压缩，并使用压缩前后记录的射频 A 扫描集通过相关技术估计相应的轴向位移矩阵。然后，使用位移矩阵来估计应变场，应变场可以解释为弹性分布的相对度量，并且可以可视化为灰度弹性图。我们研究的主要目的是在适当的逆问题解决方案及其实验探索的框架内考虑组织弹性特性的可视化和重建问题。
Ultrasonic elastographic imaging technique has been developed during last 10 years as a powerful method to image the elastic properties of soft biological tissues. The method consists of applying a small external, quasi-static compressions to the region of interest and use the set of radio frequency A-scans recorded before and after compression to estimate corresponding matrix of axial displacements by means of correlation technique. Afterwards, the displacement matrix is used to estimate the strain field, which can be interpreted as a relative measure of elasticity distribution and can be visualized as a gray scale elastogram. The main intention of our research was to consider the problem of visualization and reconstruction of tissue elastic properties within the framework of an appropriate inverse problem solution as well as its experimental exploration.
