摘要
弹性成像技术是以软组织的杨氏模量、剪切模量、应力与应变等弹性参量为成像对象的技术。伴随着光学相干层析成像(OCT)的发展,光学相干弹性成像(OCE)由于其微米级别的分辨率,实时的图像处理以及非侵入式成像得到人们的青睐。综述了OCE的分类以及当今主流的几种OCE技术及其弹性图像重构的问题。探讨了OCE中施加机械负载方法和位移估算、应变估计的方法。OCE对检测组织临床上和病理上的机械特性拥有强大的潜力,特别是在诊断癌症,心血管疾病和眼科疾病上。总结了OCE研究和发展状况,并对其发展前景进行了展望。
Elastography is a technique based on Young＇s modulus, shear modulus,stain and stress in soft tissue. With the development of optical coherent tomography （OCT）, optical coherence elastography （OCE） becomes popular because of its micron meter level resolution, real-time image processing and noninvasive imaging. The classification of OCE, several kinds of dominant OCE and elastography reconstruction are reviewed. The method of applying mechanical load and estimating displacement and strain is discussed. OCE has a great potential in detecting the clinical and pathological mechanical properties, especially in the diagnosis of cancer, cardiovascular disease and eye disease. The research development of OCE is summarized and its prospect is also discussed.
