Development of spectroscopy using next generation frequency-domain optical coherence tomography and assessment of the treatment of vulnerable plaque by this newly developed technique.

在血管内光学相干断层扫描图像序列中自动检测具有厚的新生内膜生长的支架支柱已经在文献中开发和描述，并且现在适用于新开发的频域OCT系统中的冠状动脉图像的三维重建，尽管目前冠状动脉斑块的光谱分析系统仍处于开发阶段。利用OCT图像的灰度特征识别易损斑块已有很多文献报道，而在新开发的频域OCT系统中，光谱分析技术得到完善后，将在不久的将来进行进一步的研究。

Automatic detection of stent struts with thick neointimal growth in intravascular optical coherence tomography image sequences has been developed anddescribed in a literature, and it is now applicable for three-dimensional reconstruction of coronary artery images in newly developed frequency-domain OCT system, althoughspectroscopic analysis system of coronary plaques are still under -developing at the moment. Identification of vulnerable plaques by characteristics of gray-scale OCT images have been reported in many literatures, and further investigation using spectroscopic analysis would be performed in the near future after completely developing the spectroscopy analysis in newly developed frequency-domain OCT system.
