我们提出了一种新的血管光学相干弹性成像（OCE）的多分辨率变分框架。该方法利用有关动脉壁生物力学的先验信息来产生对组织速度和应变的鲁棒估计，从而降低了传统跟踪方法对噪声和应变引起的信号去相关的敏感性。在模拟OCT图像序列和台式OCT扫描血管组织样本中证明了这种新估计器的速度和应变估计性能。(C)2004年美国光学学会。
We present a novel multi-resolution variational framework for vascular optical coherence elastography (OCE). This method exploits prior information about arterial wall biomechanics to produce robust estimates of tissue velocity and strain, reducing the sensitivity of conventional tracking methods to both noise- and strain-induced signal decorrelation. The velocity and strain estimation performance of this new estimator is demonstrated in simulated OCT image sequences and in benchtop OCT scanning of a vascular tissue sample.
