| 摘 要： | 本课题的目的是研究一种光学印压系统用于分析组织力学的性能。我们将压力传感器与光学相干层析（OCT）系统结合,分别测量印压过程中的印压力和形变。通过分析印压力和形变的曲线图,得到组织力学性能特征。初步的样品对比测试实验表明,本系统所得到的力学性能测试结果与传统的印压系统测试结果相比有很高的一致性。我们认为本系统在组织力学性能的研究中有很高的潜在应用价值。

| Abstract: | An optical indentation system was developed in this study for assessment of the mechanical properties of tissue.Optical coherence tomography (OCT) was combined with a force sensor which was used to record the deformation and force during the indentation.The mechanical properties of tissue were calculated from the analysis of the force deformation relationship.The preliminary results on phantoms showed the high correlation between the elasticity obtained by this system and the standard indentation device.Thi... |
