Broadband-excitation-based mechanical spectroscopy of highly viscous tissue-mimicking phantoms
Magdalena A. Urbańska, Sylwia M. Kolenderska, Sophia A. Rodrigues +2
Standard rheometers assess mechanical properties of viscoelastic samples up to 100~Hz, which often hinders the assessment of the local-scale dynamics. We demonstrate that high-freq…
Inverse spectroscopic optical coherence tomography (ISOCT) for characterization of particle size and concentration
James Hope, Matthew Goodwin, Frederique Vanholsbeeck
Inverse spectroscopic optical coherence tomography (IS-OCT) methods apply inverse problem formulations to acquired spectra to estimate depth-resolved sample properties. In the curr…
Impact-Induced Cartilage Damage Assessed using Polarisation-Sensitive Optical Coherence Tomography
Matthew Goodwin, Joshua Workman, Ashvin Thambyah +1
Significance: Non-invasive determination of structural changes in articular cartilage immediately after impact and rehydration provides insight into the response and recovery of th…
Quantum Optical Coherence Tomography using two photon joint spectrum detection (JS-Q-OCT)
Sylwia M. Kolenderska, Frederique Vanholsbeeck, Piotr Kolenderski
Quantum Optical Coherence Tomography (Q-OCT) is the non-classical counterpart of Optical Coherence Tomography (OCT) - a high-resolution 3D imaging technique based on white-light in…
Towards real time assessment of intramuscular fat content in meat using optical fibre-based optical coherence tomography
Abi Thampi, Sam Hitchman, Stéphane Coen +1
We consider the use of optical coherence tomography (OCT) imaging to predict the quality of meat. We find that intramuscular fat (IMF) absorbs infrared light about nine times stron…
Quantum-inspired detection for Spectral Domain Optical Coherence Tomography
Sylwia M. Kolenderska, Frédérique Vanholsbeeck, Piotr Kolenderski
The intensity levels allowed by safety standards (ANSI or ICNIRP) limit the amount of light that can be used in a clinical setting to image highly scattering or absorptive tissues…
Investigation of ephaptic interactions in peripheral nerve of sheep using 6 kHz subthreshold currents
James Hope, Narrendar Ravi Chandra, Frederique Vanholsbeeck +1
The objective of this work was to determine whether application of subthreshold currents to the peripheral nerve increases the excitability of the underlying nerve fibres, and how…
Refractive index measurements of multicellular tumour spheroids using optical coherence tomography: dependence on growth phase and size
Neelam Hari, Priyanka Patel, Jacqueline Ross +2
Knowledge of optical properties, such as the refractive index (RI), of biological tissues is important in optical imaging, as they influence the distribution and propagation of lig…
Bourdieu, networks, and movements: Using the concepts of habitus, field and capital to understand a network analysis of gender differences in undergraduate physics
Steven Martin Turnbull, Frédérique Vanholsbeeck, Kirsten Locke +1
Current trends suggest that significant gender disparities exist within Science, Technology, Engineering, and Mathematics (STEM) education at university, with female students being…
Rapid and cost-effective evaluation of bacterial viability using fluorescence spectroscopy
Fang Ou, Cushla McGoverin, Simon Swift +1
The fluorescence spectra of bacterial samples stained with SYTO 9 and propidium iodide (PI) were used to monitor bacterial viability. Stained mixtures of live and dead Escherichia…
Near real-time enumeration of live and dead bacteria using a fibre-based spectroscopic device
Fang Ou, Cushla McGoverin, Simon Swift +1
A rapid, cost-effective and easy method that allows on-site determination of the concentration of live and dead bacterial cells using a fibre-based spectroscopic device (the optrod…
Extracting morphometric information from rat sciatic nerve using optical coherence tomography
J. Hope, B. Brauer, S. Amirapu +2
We apply three optical coherence tomography (OCT) image analysis techniques to extract morphometric information from OCT images obtained on peripheral nerves of rat. The accuracy o…
A model of electrical impedance tomography on peripheral nerves for a neural-prosthetic control interface
J. Hope, F. Vanholsbeeck, A. McDaid
Objective: A model is presented to evaluate the viability of using electrical impedance tomography (EIT) with a nerve cuff to record neural activity in peripheral nerves. Approach:…
Quantifying birefringence in the bovine model of early osteoarthritis using polarisation-sensitive optical coherence tomography and mechanical indentation
Matthew Goodwin, Bastian Bräuer, Stephen lewis +2
Recent studies have shown potential for using polarisation sensitive optical coherence tomography (PS-OCT) to study cartilage morphology, and to be potentially used as an in-vivo,…
Dispersion mapping as a simple postprocessing step for Fourier domain Optical Coherence Tomography data
Sylwia M. Kolenderska, Bastian Braeuer, Frederique Vanholsbeeck
Optical Coherence Tomography (OCT) was originally conceived as a volumetric imaging method. Quickly, OCT images went beyond structural data and started to provide functional inform…
Absolute bacterial cell enumeration using flow cytometry
Fang Ou, Cushla McGoverin, Simon Swift +1
Aim: To evaluate a flow cytometry protocol that uses reference beads for the enumeration of live and dead bacteria present in a mixture. Methods and Results: Mixtures of live and d…
