Novel Techniques for Resolution Improvement in Optical Coherence Tomography

Title: Novel Techniques for Resolution Improvement in Optical Coherence Tomography

Abstract: Optical Coherence Tomography (OCT), a method for cross sectional tissue imaging, is gaining significant ground as diagnostic tool in various fields. However many early disease changes remain below the resolution of the technique. In OCT the resolution is fundamentally limited by the spectrum of the laser source and the optics used. Enhancements can only be marginal since the spectral increase required for further axial resolution improvement cannot be supported even by the highest end lasers. The lateral resolution of OCT can be improved by use of high numerical aperture (NA) objectives. However, use of a high NA objective restricts the depth of focus. In this presentation we propose some novel methods for axial and lateral resolution improvement which are independent from the above limitations, providing the opportunity for cellular and subcellular resolution imaging, without increasing the cost and complexity of the system. A method for axial resolution improvement was developed, which was based on the modulation of the axial PSF of the system. With this method the axial resolution could be improved by a factor of 7. The application of this method in Time Domain OCT differs significantly from that in Frequency Domain OCT systems. However different formulations have been developed for both. Their mechanical basis and experimental validation will be presented. Also a method for lateral resolution improvement based on the oversampling of the OCT images was developed. The information in the oversampled OCT images was used to estimate the locations of multiple scatterers, assuming each contributes a weighted portion to the detected signal. This method was applied to laterally oversampled OCT images, and a resolution improvement of a factor of 3.7 was experimentally demonstrated. The development of the above methods can significantly improve the resolution of OCT images allowing imaging of diagnostically crucial cellular level characteristics. Such technological improvement can increase the effectiveness of OCT as a tool for diagnosis of very early cancer and other diseases

Abstract:

Motivated by the increasing dependence of many systems on battery energy (e.g.,
wireless sensor networks, mobile robots, electric vehicles), we will discuss the problem of optimally controlling how to discharge and recharge a non-ideal battery so as to maximize the work it can perform over a given time period and still maintain a desired final energy level.
Modeling a battery as a dynamic system, we adopt a Kinetic Battery Model (KBM) and formulate a finite-horizon optimal control problem. The solution is shown to be of bang–bang type with the property that the battery is always in recharging mode during the last part of the interval. We then extend the problem to settings where recharging is only occasionally feasible and show that it can be reduced to a nonlinear optimization problem. We further study the problem of optimally controlling a set of non-ideal rechargeable batteries that can be shared to perform a given amount of work over some specified time period. In this case, we seek to
maximize the minimum residual energy among all batteries at the end of this period. We show that the optimal solution must result in equal residual energies for all batteries as long as such a policy is feasible. This simplifies the task of subsequently deriving explicit solutions for the problem.

Multi-process Dynamic Linear modeling for tumor growth evolution

Abstract: The mathematical modeling of tumor growth and progression has been thoroughly studied and many such models exist in the literature. The majority of these modeling techniques are formulated in a deterministic context, thus lacking any information regarding the uncertainty of the predicted future state of the tumor size. Many are theoretically well defined and can have useful practical applications; for example such models can be used to define general optimal treatment protocols through onstrained optimization. However, modern healthcare is continuously becoming less general and more personalized. In this paper we propose a sequential probabilistic mixture model for individualized tumor growth forecasting. The model uses prior information from the general population and becomes more individualized as more observations from the subject are sequentially taken into account by the model. In our extensive simulation study we illustrated the superiority, under uncertainty, of the suggested multi-process dynamic linear model against the single process alternative. The validation of our model was performed with experimental data from mice and the results show that after few observations from a tumor are obtained and included in the model, the latter becomes both more individualized, in the sense that it adjusts its parameters in order to explain the growth of each individual tumor and much more e cient ffi in terms of precision regarding the prediction of the tumor size.

Biography: Dr Achilleas Achilleos completed his undergraduate degree in Mathematics, Operational Research, Statistics and Economics (M.O.R.S.E.) at the Department of Mathematics at the University of Warwick in 2006. He then earned a full scholarship to study an MSc in Statistical Science in the London School of Economic and Political Science. In 2007, Achilleas joined the Department of Mathematics at the University of Bristol for a PhD in Applied Statistics. He completed his PhD in 2011. He is currently working in the Research Center for Intelligent Systems and Networks (K.I.O.S.) at the University of Cyprus for a project concerning mathematical modeling of cancer progression and development of therapy strategies with model-based control methods. Among his major research interests are smoothing parameter selection for kernel density and regression estimation in the presence of measurement error, linear dynamic modeling with Bayesian forecasting, multilevel modeling, and probabilistic reasoning and inference under uncertainty using bayesian causality networks.

Routing and Wavelength Assignment in Optical Networks

Abstract: In a wavelength division multiplexing (WDM) network, each fiber link carries high-rate traffic at several different wavelengths, thus creating multiple channels within a single fiber. The most common architecture utilized for establishing communication in WDM optical networks is wavelength routing, where optical pulse-trains are transmitted through lightpaths, that is, all-optical WDM channels that may span multiple consecutive fibers. An important problem in optical networks is to select the routes for the requested connections and to assign wavelengths on each of the links along these routes. This is known as the routing and wavelength assignment (RWA) problem. In a transparent or translucent network, where the signal on a lightpath remains in the optical domain, the quality of transmission (QoT) is significantly affected by physical limitations of fibers and optical components. The RWA problem in the presence of physical layer impairments is referred as Impairment aware (IA-) RWA. In this talk we will present RWA algorithms that take into account physical layer impairments and other constraints and can be used during optical network planning and network operation.
