fa Refractive Index Correction in Optical Coherence Tomography Images تخصصی Special پژوهشي Research <p dir="ltr"><em>Optical coherence tomography (OCT) imaging is a high resolution and non-invasive imaging modality that provides cross-sectional images of a tissue. The time of fly in the signal processing of the OCT system is calculated based on a constant refractive index. Different layers of the complex tissues however have different refractive indices. This issue prompts pixels in the image to be misplaced and that makes it difficult for the physicians to have an accurate diagnosis of abnormalities based on OCT imaging. In this paper, we propose a novel post-processing method to correct for the refractive index.&nbsp; The proposed method is based on imaging a tissue to which a needle has penetrated.</em></p> <p dir="ltr"><em>Optical coherence tomography (OCT) imaging is a high resolution and non-invasive imaging modality that provides cross-sectional images of a tissue.
