作者提出了一种组织多普勒光学相干弹性成像（tDOCE）方法来实时成像组织运动，应变率和软组织应变。该方法利用组织运动引起的光学相干干涉图中的多普勒效应，测量连续A扫描之间的相位变化来解决瞬时组织位移。tDOCE系统能够实时显示组织在动态压缩下的应变率和应变图。该系统通过使用具有已知机械性能的异质组织体来证明。
The authors present a tissue Doppler optical coherence elastography (tDOCE) method to image tissue movements, strain rates, and strains of soft tissue in real time. The method exploits the Doppler effect in optical coherence interferograms induced by tissue motion and measures the phase changes between successive A scans to resolve the instantaneous tissue displacement. The tDOCE system is capable of displaying the strain rates and strain maps of tissue subjected to a dynamic compression in real time. The system is demonstrated by the use of a heterogeneous tissue phantom with known mechanical properties.
