Optical imaging techniques and systems provide high-fidelity optical imaging based on optical coherence tomographic imaging and can be used for optical imaging in ophthalmic surgery and imaging-guided surgery. One method for imaging an eye includes positioning the eye relative to a Spectral Domain Optical Coherence Tomographic (SD-OCT) imaging system, the eye having a first and a second structure, and imaging the eye with the SD-OCT imaging system by selecting one of a direct image and a mirror image of the first eye-structure and generating a first image-portion corresponding to the selected image of the first eye-structure, selecting one of a direct image and a mirror image of the second eye-structure and generating a first image-portion corresponding to the selected image of the second eye-structure, and suppressing the non-selected images of the first and second structures.本說明書揭示一種光學造影技術與系統,其根據光學斷層掃描造影,提供高傳真光學造影,可用於眼科手術以及造影導引手術內的光學造影。一眼睛造影的方法包括:相對於一頻域光學斷層掃描(SD-OCT)造影系統定位該眼睛,該眼睛具有一第一和一第二結構;以及利用下列方式使用該SD-OCT造影系統對該眼睛造影:選取該第一眼睛結構的直接影像和鏡射影像的其中之一,並且產生對應至該第一眼睛結構的所選影像之第一影像部分;選取該第二眼睛結構的直接影像和鏡射影像的其中之一,並且產生對應至該第二眼睛結構的所選影像之第一影像部分;以及抑制該第一和第二結構的該等未選取影像。1...眼睛301...手術雷射引擎302...物鏡310...光源320...分光器330...分光器340...參考鏡子350...干涉分析儀351...光譜分解器353...感測器或像素陣列357...FFT處理器359...影像產生器361...造影光束362...參考光束363...干涉光束
