In this paper, we present a new approach to contrast-agent-free angiographic visualization in optical coherence tomography (OCT). The proposed approach has much in common with imaging of local interframe strains in OCT-based elastography and utilizes

We present a real-time realization of OCT-based elastographic mapping local strains and distribution of the Young’s modulus in biological tissues, which is in high demand for biomedical usage. The described variant exploits the principle of Compres

We present a robust semi-analytical multi-factor model of OCT-scan formation with rigorous accounting for the beam-focusing effects. It is based on numerical summation of the contributions of the localized sub-resolution scatterers, accounting for va

Numerical beam refocusing in OCT is used to increase lateral resolution in the out-of-focus areas for strongly focused beams. However, this approach is based on overlapping lateral scanning in the assumption of the same scatterers positions. In the p

A computationally efficient and fairly realistic model of OCT-scan formation in spectral-domain optical coherence tomography is described. The model is based on the approximation of discrete scatterers and ballistic character of scattering, these app
