【摘要】：正随着科技的进步和技术的不断改进,光学相干断层扫描系统(opticalcoherencetomography,OCT)目前已实现从时域向频域的跨越,可以实现自然瞳孔下直接进行眼底状态的断层和三维立体检查,光源的改进和扫描速度的提高实现了更大范围的区域扫描,为后续的三维重建奠定基础。波长为1310nm的时域OCT扫描速度较慢且对视网膜组织结构成像分辨率较低,而波长为830~870nm的频域OCT(SD-OCT)不仅提高了图像的分辨率,而且在高速扫描下实现了区域扫描后的三维重建。总之,对于后节OCT而言,一方面频域已完全取代时域技术,另一方面临床应用
[Abstract]:With the progress of science and technology and the continuous improvement of technology, optical coherence tomography Oct (Oct) has been realized from the time domain to the frequency domain, can directly carry out the state of the eye floor under the natural pupil of the fault and three-dimensional inspection. The improvement of the light source and the increase of the scanning speed can achieve a wider range of area scanning and lay the foundation for the subsequent 3D reconstruction. Time domain Oct with wavelength of 1310nm is slower and the resolution of retinal tissue structure imaging is lower. Frequency domain Oct (SD-Oct) with wavelength of 830~870nm not only improves the resolution of image, but also realizes the 3D reconstruction after regional scanning at high speed. In a word, for posterior Oct, the frequency domain has completely replaced the time domain technology on the one hand, and the clinical application on the other.
