OCT: Serous PEDs (Figure 1B) appear as well-demarcated, abrupt elevations of the RPE with a homogenously hyporeflective sub-RPE space. Enhanced depth imaging (EDI) OCT is useful to determine whether serous PEDs are caused by AMD (normal subfoveal choroidal thickness) or by CSC (increased subfoveal choroidal thickness).

This project aims to produce an easy to use tool to calibrate any SD or SS-OCT. The processing is based on Attendu et al. "Simple and robust calibration procedure for k-linearization and dispersion compensation in optical coherence tomography." (doi: 10.1117/1.JBO.24.5.056001)

OCTproZ is an open source software for optical coherence tomography (OCT) processing and visualization. A plug-in system enables the integration of custom OCT systems and software modules. The output windows in the screenshot above show OCT images of a strawberry. Live OCT visualization with OCTproZ: Laser cutting a spring onion.

2019年2月21日 · 综合上述研究成果，文教授指出PED表面色素沉积可表现为OCTA上新生血管伪影，该伪影可能是一种被色素沉积局部放大的去相关投影伪影，为避免误诊及不必要的治疗，在临床OCTA图像阅读时应注意辨识，并与多模式影像相互验证。 （来源：《国际眼科时讯》编辑部） 版权属《国际眼科时讯》所有。 欢迎个人转发分享。 其他任何媒体、网站如需转载或引用本网版权所有之内容，须经本网同意并在文章顶部注明“转自《国际眼科时讯》” 返回搜狐，查看更 …

2019年10月12日 · To effectively provide information of coronary artery stenosis, we propose a novel hybrid framework which includes the faster R-CNN, fourth-order partial differential equation and global-local active contour model (FPDE-GLACM). This framework can efficiently detect and segment the plaque area in Speckle noise-contaminated IV-OCT images.

2015年7月2日 · Doppler OCT (D-OCT) which is also called optical Doppler tomography (ODT) is a combination of an OCT imaging system and laser Doppler flowmetry. This system allows for the quantitative imaging of fluid flow in a highly scattering medium; such as monitoring in vivo blood flow beneath the skin .

2021年10月25日 · In this work we leverage physics-informed deep operator networks (DeepONets) -- a self-supervised framework for learning the solution operator of parametric PDEs -- to build fast and differentiable surrogates for rapidly solving PDE-constrained optimization problems, even in the absence of any paired input-output training data.

A comparison between two nonlinear diffusion methods for denoising OCT images is performed. Specifically, we compare and contrast the performance of the traditional nonlinear Perona-Malik filter with a complex diffusion filter that has been recently introduced by Gilboa et al..

2022年8月8日 · On the basis of a fourth-order partial differential equation (PDE) and active contour (AC) model, a novel adaptive image segmentation algorithm PDE-AC was constructed and used for OCT image processing.
