Imaging-formulation-based numerical speckle reduction for optical coherence tomography
Xibo Wang, Shuichi Makita, Nobuhisa Tateno +6
Speckle is an intrinsic pattern in optical coherence tomography (OCT) that obscures fine image features and degrades effective resolution. In this study, we propose a numerical spe…
Image-based investigation of the zebrafish developmental process using in vivo dynamic and multi-contrast optical coherence tomography
Cunyou Bao, Aiyi Sui, Ibrahim Abd El-Sadek +5
We demonstrate in vivo dynamic optical coherence tomography (DOCT) imaging of zebrafish development from 2 weeks to 12 months post-fertilization, integrated with polarization-sensi…
Neural-network-based high-speed and high-definition full-field dynamic optical coherence tomography
Suzuyo Komeda, Nobuhisa Tateno, Yusong Liu +7
A neural-network (NN)-based method for high-speed, high-definition dynamic optical coherence tomography (DOCT) using full-field swept-source optical coherence microscopy (FF-SS-OCM…
Theoretical analysis of performance limitation of computational refocusing in optical coherence tomography
Yue Zhu, Shuichi Makita, Naoki Fukutake +1
High-numerical-aperture optical coherence tomography (OCT) enables sub-cellular imaging but faces a trade-off between lateral resolution and depth of focus. Computational refocusin…
Dynamic full-field swept-source optical coherence microscope for cellular-resolution, long-depth, and intratissue-activity imaging
Nobuhisa Tateno, Yue Zhu, Suzuyo Komeda +8
Optical coherence tomography (OCT) microscope (OCM) uses a high-numerical-aperture objective to achieve cellular-level lateral resolution. However, its practical imaging depth rang…
Dynamic optical coherence tomography algorithm for label-free assessment of swiftness and occupancy of intratissue moving scatterers
Rion Morishita, Pradipta Mukherjee, Ibrahim Abd El-Sadek +8
Dynamic optical coherence tomography (DOCT) statistically analyzes fluctuations in time-sequential OCT signals, enabling label-free and three-dimensional visualization of intratiss…
