摘要：光学相干断层成像 (OCT)能够对活体组织的复杂结构进行成像，但是缺少功能性信息。 文中提出了一种动态全场的OCT技术，非侵入性地对多功能干细胞诱生的视网膜细胞器进行活体成像。

Optical coherence tomography (OCT) is a high-resolution imaging technique with most of its applications in medicine and biology. OCT uses coherent near-infrared light to obtain micrometer-level depth resolved images of biological tissue or other scattering media.

Jul 18, 2024 · 光学相干断层扫描（OCT）是一种三维成像技术，可以在散射介质中进行高分辨率成像，无需接触样品或使用任何耦合介质。 OCT的横向成像分辨率可达到几微米，成像深度可达几毫米。 OCT能够提供样品表面轮廓和次表面结构（即表面以下的结构）及样品均匀性的信息，从而实时提供准确的信息用于诊断、监测和现场过程反馈。 因此，OCT已经在眼科、皮肤科、血管造影等生物成像领域得到了应用，并且在材料检测和无损检测中作为超声波的强大替代技术。 OCT …

Sep 26, 2024 · Optical coherence tomography (OCT) and optical coherence tomography angiography (OCTA) are non-invasive imaging tests. They use light waves to take cross-section pictures of your retina. With OCT, your ophthalmologist can see each of the retina’s distinctive layers and the optic nerve fiber layer.

Aug 17, 2020 · Optical coherence tomography (OCT) is commonly used in biology and medicine to obtain 3D images of microstructures in tissue. OCT contrast arises from the local...

Sep 27, 2021 · Optical coherence tomography (OCT), first proposed by David in 1991, is a novel three-dimensional (3D) imaging technology with noninvasive, high-resolution, and low-cost characteristics, which can perform high-definition cross-sectional imaging of the biological tissue in situ by measuring the reflected light signal, especially for transparent ...

Dec 6, 2024 · 1.光学相干断层扫描 （OCT） 成像技术基于低相干光的应用，用于以微米和亚微米级分辨率捕获图像，包括三维 （3D） 图像 [1]。 OCT 成像 技术使用光波（通常具有长波长）来制作表现出光散射的介质的横截面图像。

Aug 20, 2024 · OCTCube-M first developed OCTCube, a 3D foundation model pre-trained on 26,685 3D OCT volumes encompassing 1.62 million 2D OCT images. It then exploits a novel multi-modal contrastive learning framework COEP to integrate other retinal imaging modalities, such as fundus autofluorescence and infrared retinal imaging, into OCTCube, efficiently ...
