急性冠状动脉事件如血栓形成的主要原因是动脉粥样硬化斑块的破裂。典型的血管内光学相干断层扫描(IVOCT)成像系统采用1.3 μm扫频光源激光,通常用于识别斑块的纤维帽厚度,但无法提供足够的深度穿透来分辨脂质池的大小。在这里,我们提出了一种新型的IVOCT系统,具有1.7 μm中心波长扫描光源,由于波长较长,可以很容易地穿透到组织更深处,并且由于1.7 μm处的脂质吸收光谱,可以更好地识别斑块。使用该系统,我们已经成像的人冠状动脉,以评估新的光学相干断层扫描系统的性能,并验证了苏木精和伊红(H&E)组织学的结果。显著改善的成像深度和更好的识别灵敏度表明,1.7 μm OCT系统具有巨大的潜力,可以进一步转化为动脉粥样硬化表征的体内应用。
The main cause of acute coronary events, such as thrombosis, is the rupture of atherosclerotic plaques. Typical intravascular optical coherence tomography (IVOCT) imaging systems that utilize a 1.3 μm swept source laser are often used for identifying fibrous cap thickness of plaques, yet cannot provide adequate depth penetration to resolve the size of the lipid pool. Here, we present a novel  IVOCT system with a 1.7 μm center wavelength swept light source that can readily penetrate deeper into the tissue because of the longer wavelength and allows for better identification of plaques due to the lipid absorption spectrum at 1.7 μm. Using this system, we have imaged a human coronary artery to evaluate the performance of the novel OCT system and verified the results by hematoxylin and eosin (H&E) histology. The significantly improved imaging depth and better identification sensitivity suggest that the 1.7 μm OCT system holds great potential  that can be further translated for in-vivo applications of atherosclerosis characterization.
