Book Description
This dissertation describes the design, fabrication and testing of an oblique incidence diffuse reflectance spectrometry (OIDRS) system for in-vivo and noninvasive detection of epithelial cancer. Two probes were fabricated using micromachining technology, which plays a significant role in the probe development by enabling device miniaturization, low-cost fabrication and precise assembly. The fist probe was developed and clinically tested for skin cancer detection. This probe consists of three source fibers, two linear array of collection fibers and four micromachined positioning devices for accurate alignment of the fibers. The spatially resolved diffuse reflectance spectra from 167 pigmented and 78 non-pigmented skin abnormalities were measured and used to design a set of classifiers to separate them into benign or malignant ones. These classifiers perform with an overall classification rate of 91%. The absorption and reduced scattering coefficient spectra were estimated to link the anatomic and physiologic properties of the lesions with the optical diagnosis. The melanoma cases presented larger average absorption and reduced scattering spectra than the dysplastic and benign ones. A second probe was designed to demonstrate the feasibility of a miniaturized?side viewing? optical sensor probe for OIDRS. The sensor probe consists of a lithographically patterned polymer waveguides chip and two micromachined positioning substrates. This miniaturize probe was used to measure twenty ex-vivo esophageal samples. Two statistical classifiers were designed to separate the esophageal cases. The first one distinguishes benign and low dysplastic from high dysplastic and cancerous lesions. The second classifier separates benign lesions from low dysplastic ones. Both classifiers generated a classification rate of 100%.

Optical Spectroscopy in Non-invasive Detection of Oral Cancer

Optical Spectroscopy in Non-invasive Detection of Oral Cancer PDF Author: J. L. Jayanthi
Publisher: LAP Lambert Academic Publishing
ISBN: 9783659366598
Category :
Languages : en
Pages : 156

Book Description
Oral cancer is one of the significant global health concerns with reports of more than ten million new cases and mortality of six million, each year. The current clinical procedure for oral cancer detection is visual examination followed by histopathological analysis of biopsied lesion. However, this procedure often leads to multiple biopsies due to the difficulty in identifying the most malignant site for biopsy and that the procedure is invasive and time-consuming in nature. This book presents an overview of non-invasive and real-time diagnostic techniques based on tissue fluorescence and diffuse reflectance to detect oral cancer using both point monitoring and multi-spectral imaging. The clinical study results of diffuse reflectance spectral imaging at oxygenated hemoglobin absorption dips establish the potential of this imaging modality in detecting squamous cell carcinoma affecting epithelial tissues of various organs and for biopsy guidance. The ability to observe disease onset and progression through non-invasive and cost effective screening methods at the population level would help to implement prevention and treatment strategies at an early stage.

Languages : en
Pages : 654

Book Description
Biomedical Optics in Otorhinolaryngology: Head and Neck Surgery gives an overview of current technology in biomedical optics relevant to the field of Otorhinolaryngology and head and neck surgery. It provides a comprehensive source of knowledge for researchers and active clinicians seeking information on the principles and practical use of novel diagnostic and therapeutic technology. While most books focus exclusively on laser surgery, which has been largely unchanged for the past 15 years, optical diagnostics and head and neck PDT (photodynamic therapy) are usually entirely overlooked. This book contains a basic introduction into the physics of light and its propagation, lasers and low-coherent light sources, and photon-tissue interaction in relation to therapeutic and diagnostic use. The principles of various imaging techniques are also discussed ( i.e. optical coherence tomography in its variations), as well as the principles and practice of lasers for surgical use on the therapeutic side.

Book Description
The present thesis aimed to evaluate the performance of non-invasive optical method for bladder pre- and early- cancer detection by means of diffuse-reflected laser light analysis. The analysis of light distribution at the surface of multi-layered bladder phantoms with different scattering and absorption properties showed that the changes in the optical properties lead to increase or decrease of the diffuse-reflected light spot area, detectable by a video camera. It was also determined, that the presented method is capable of detection of the photosensitizer accumulation, and can be applied for both (diffuse-reflected laser and fluorescence) studies simultaneously. The calculations for spherical and ?coated?-spherical tissue scatterers, based on the electromagnetic wave theory, allowed for obtaining optical parameters of three-layered biological phantoms and of bladder tissues at different states. These parameters served as inputs for Monte Carlo simulations, which provided us with matrices of diffuse-reflected light distributions. The study showed that the measurements of non-polarized back-scattered laser light can provide useful information on the tissue state.

Book Description
Colorectal cancer is the 4th most common and 2nd deadliest cancer. Problems exist with predicting which patients will respond best to certain therapy regimens. Diffuse reflectance spectroscopy has been suggested as a candidate to optically monitor a patient's early response to therapy and has been received favorably in experimentally managing other cancers such as breast and skin. In this dissertation, two diffuse reflectance spectroscopy probes were designed: one with a combined high-resolution microendoscopy modality, and one that was optimized for acquiring data from subcutaneous murine tumors. For both probes, percent errors for estimating tissue optical properties (reduced scattering coefficient and absorption coefficient) were less than 5% and 10%, respectively. Then, studies on tissue-simulating phantoms were performed to test probe sensitivity and to serve as testing platforms for investigators in biomedical optics. Next, the diffuse reflectance spectroscopy probe was applied to subcutaneous murine colon tumors (n=61) undergoing either antibody immunotherapy or standard 5-fluorouracil chemotherapy. Mice treated with a combination of these therapies showed reduced tumor growth compared to saline control, isotype control, immunotherapy, and chemotherapy groups (p

Category : Technology & Engineering
Languages : en
Pages : 729

Book Description
Edited by prominent researchers and with contributions from experts in their individual areas, Intelligent Energy Field Manufacturing: Interdisciplinary Process Innovations explores a new philosophy of engineering. An in-depth introduction to Intelligent Energy Field Manufacturing (EFM), this book explores a fresh engineering methodology that not only integrates but goes beyond methodologies such as Design for Six Sigma, Lean Manufacturing, Concurrent Engineering, TRIZ, green and sustainable manufacturing, and more. This book gives a systematic introduction to classic non-mechanical manufacturing processes as well as offering big pictures of some technical frontiers in modern engineering. The book suggests that any manufacturing process is actually a process of injecting human intelligence into the interaction between material and the various energy fields in order to transfer the material into desired configurations. It discusses technological innovation, dynamic M-PIE flows, the generalities of energy fields, logic functional materials and intelligence, the open scheme of intelligent EFM implementation, and the principles of intelligent EFM. The book takes a highly interdisciplinary approach that includes research frontiers such as micro/nano fabrication, high strain rate processes, laser shock forming, materials science and engineering, bioengineering, etc., in addition to a detailed treatment of the so called "non-traditional" manufacturing processes, which covers waterjet machining, laser material processing, ultrasonic material processing, EDM/ECM, etc. Filled with illustrative pictures, figures, and tables that make technical materials more absorbable, the book cuts across multiple engineering disciplines. The majority of books in this area report the facts of proven knowledge, while the behind-the-scenes thinking is usually neglected. This book examines the big picture of manufacturing in depth before diving into the deta
