摘要
弹性是一种描述物质物理意义的重要参数,在医学上,弹性的变化往往和病变联系在一起。因此弹性成像被广泛用来表征生物组织机械性能的变化。传统的弹性成像存在分辨率低,穿透深度低或者侵入式测量等问题。而光学成像技术以其无损,非接触,非侵入性和高分辨率、高穿透深度等优势越来越受到研究人员的青睐。主要介绍了几种可用于弹性性能测量的光学成像技术、光学相干层析技术、光学相干弹性成像技术以及光声成像技术,分别介绍了它们的成像原理、研究进展以及应用场景。
Elasticity is an important parameter that describes the physical meaning of matter,and in medicine,changes in elasticity are often associated with pathological changes.Therefore,elastic imaging is widely used to characterize changes in the mechanical properties of biological tissues.Traditional elastic imaging has problems such as low resolution,low penetration depth,or invasive measurement.Optical imaging technology is increasingly favored by researchers due to its advantages of non-destructive,non-contact,non-invasive,and high-resolution high penetration depth.Several optical imaging techniques that can be used for elastic performance measurement such as optical coherence tomography,optical coherence elastic imaging,and photoacoustic imaging are mainly introduced.
