WebAug 14, 2024 · Optical coherence tomography (OCT) is a non-contact imaging technique which generates cross-sectional images of tissue with high resolution. Therefore it is especially valuable in organs, where traditional microscopic tissue diagnosis by means of biopsy is not available—such as the human eye. Since OCT is completely noninvasive, it …
WebMay 5, 2024 · Recently, we and others could demonstrate dynamic contrast with the more widely used scanning frequency-domain OCT (FD-OCT), which provides high-quality sectional images (B-scans) and high flexibility of choosing the image field [16,17]. The aim of this work is to show the added value of dynamic contrast for OCT imaging of airways. WebDynamic contrast makes microscopic FD-OCT a promising tool for the histological analysis of unstained tissues. While optical coherence tomography (OCT) provides a …
WebThe putative cause of the dynamic OCT signal is ATP-dependent motion of cellular structures in a sub-micrometer range, which provides histology-like contrast. Here we … WebOptical coherence tomography (OCT) with axial and lateral resolution of 1 µm, termed microscopic OCT (mOCT), is suited for the investigation of dynamic processes on cellular level. An improvement in contrast to visualize cellular structures can be achieved by evaluating inherent signal fluctuation. This so-called dynamic contrast was recently …
