NIR Reflectance Imaging of Biological Tissue Using Multiple Sources and Detectors

ICTMI 2017

The optical characteristics of biological tissues vary in health and diseases. By analysis of photons scattering process by Monte Carlo simulation (MCS) the inhomogeneities in tissues are to be identified and their images reconstructed.Digital phantoms with goat's heart as a control tissue embedded with inhomogeneities adipose (high scattering) and spleen (high absorption) are simulated. The phantoms considered are - (a) simulation of the developed stage of inhomogeneity by inclusion of adipose and spleen tissues in control and (b) its onset stage by increasing the optical parameters by 10% at fixed locations in control tissue. These phantoms are scanned by simulated system, consisting of nine ports for photon injection and backscattered photons from each port are received by three ports located at 2, 4 and 6mm from the injecting port, placed in the direction of x-axis. By the data collected from the entire surface, by processing, three grey-scale images are constructed. For localization of inhomogeneities these images are scanned in terms of normalized backscattered intensity (NBI).The images obtained by MCS with 1 million photons, with error minimized, at respective ports, show the presence of inhomogeneities at various depths, which is further supported by the increase or decrease in the NBI compared to that of control for adipose or spleen, respectively. The increase or decrease is more at first port compared to others. The inhomogeneities located at 2mm below the surface are better identified by the receiving port located at 2mm on the surface. The same applies to inhomogeneities located at 4 and 6mm, respectively.The present simulated system not only shows the presence of inhomogeneties at various depths in tissue phantom but also presents their characteristics.

Simulation of laser backscattering system for imaging of inhomogeneity/tumor in biological tissues

Power efficient transmission has received significant attention among cellular network operators to reduce the environmental effects and to maintain profitability. Since the evolved node base station (eNB) is the primary power consumer in the cellular network, endeavours have been made to study eNB power consumption and to find approaches to enhance power efficiency. The concept of multi-hop relay (MHR) network is introduced in 4G and beyond standards to reduce the deployment cost and transmission power while improving the coverage and capacity. Here relay stations (RS) are also deployed by the network operators along with eNBs to maximize the average spectral efficiency per user. But the deployment of RSs is not standardized. Improper RS deployment leads to severe quality loss. In this work, RS deployment based on cost (RDBC) approach is utilized which identifies the RS deployment combinations and deploys different types of RSs to maximize the system quality. Through simulations, it is validated that the proposed approach maximizes the transmission quality, coverage and effectiveness in power consumption and minimizes the deployment cost and interference when compared to many of the conventional RS deployment approaches. The scheme utilized ensures power efficient transmission and acts as a potential candidate for green radio communication. © 2016 River Publishers.
