Available in PDF, EPUB and Kindle. Book excerpt: The goal of the research project, "Time-Resolved and Spectroscopic Three-Dimensional Optical Breast Tomography," was to develop a safe and affordable breast cancer detection modality that uses noninvasive near-infrared (NIR) light for imaging and diagnosing tumors in human breast with high resolution and specificity. In order to realize that goal three different approaches were developed. These are Optical Tomography using Independent Component Analysis (OPTICA), Round Trip Matrix (RTM) approach, and Center of Intensity Time Gated Imaging (CITGI). OPTICA is the most developed of these approaches. It has been demonstrated that OPTICA can detect, obtain the threedimensional location information and cross-section images of small absorbing, scattering, and fluorescent targets in model media, and tumor(s) in realistic model breast with considerable accuracy. Further accomplishments include development of a forward model for determining the backscattered polarized light intensity distribution, and initial development of a technique to determine scattering coefficient, absorption coefficient, and anisotropy factor (g) of breast tissue specimens. Besides detection and localization of tumors in breast, these results may have potential applications in optical biopsy, and lumpectomy. The graduate student supported by the project received his Ph. D., adding another scientist to the ongoing fight against breast cancer.

Download or read book Advanced Therapy of Breast Disease written by S. Eva Singletary and published by PMPH-USA. This book was released on 2004 with total page 902 pages. Available in PDF, EPUB and Kindle. Book excerpt: The information surveyed in this volulme is designed to provide the clinician with an expert overview of the current state of the art in breast cancer management. It should provide at least a flavor of the major paradigm shift that is occurring in this rapidly evolving field. Breast cancer management is moving away from a "kill or cure" model and advancing toward a model focused on strategies of prevention and of long-term management of breast cancer as a chronic disease. The acceptance of this new paradigm by patients and clinicians alike will represent a major focus for the twenty-first century.

Download or read book Diffuse Optical Tomography written by Huabei Jiang and published by CRC Press. This book was released on 2018-09-03 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written by an authority involved in the field since its nascent stages, Diffuse Optical Tomography: Principles and Applications is a long-awaited profile of a revolutionary imaging method. Diffuse Optical Tomography (DOT) provides spatial distributions of intrinsic tissue optical properties or molecular contrast agents through model-based reconstruction algorithms using NIR measurements along or near the boundary of tissue. Despite the practical value of DOT, many engineers from electrical or applied mathematics backgrounds do not have a sufficient understanding of its vast clinical applications and portability value, or its uncommon advantages as a tool for obtaining functional, cellular, and molecular parameters. A collection of the author’s research and experience, this book fuses historical perspective and experiential anecdotes with fundamental principles and vital technical information needed to successfully apply this technology—particularly in medical imaging. This reference finally outlines how to use DOT to create experimental image systems and adapt the results of laboratory studies for use in clinical applications including: Early-stage detection of breast tumors and prostate cancer "Real-time" functional brain imaging Joint imaging to treat progressive diseases such as arthritis Monitoring of tumor response New contrast mechanisms and multimodality methods This book covers almost every aspect of DOT—including reconstruction algorithms based on nonlinear iterative Newton methods, instrumentation and calibration methods in both continuous-wave and frequency domains, and important issues of imaging contrast and spatial resolution. It also addresses phantom experiments and the development of various image-enhancing schemes, and it describes reconstruction methods based on contrast agents and fluorescence DOT. Offering a concise description of the particular problems involved in optical tomography, this reference illustrates DOT’s fundamental foundations and the principle of image reconstruction. It thoroughly explores computational methods, forward mathematical models, and inverse strategies, clearly illustrating solutions to key equations.

Book excerpt: The research carried out during the current reporting period involved: (a) extending the cumulant solution of radiative transfer to planar geometries and comparing with Monte Carlo simulations; (b)developing and enhancing the 3D tomographic image reconstruction algorithm by using the cumulant transport model; (c) developing the criterion of the optimal regularization for image reconstruction dependent on the noise presented in measurements; and (d) deriving the nonlinear correction factor for optical imaging due to multiple passages of an absorption inhomogeneity by a photon and providing a measure of the efficacy of linear inversion schemes. The cumulant transport model was found to provide a more accurate model than the conventional diffusion model for image reconstruction in turbid media such as human breasts. The proper modeling of the noise and the appropriate regularization improves the quality of image reconstruction. The nonlinear effect of the multiple passages of an absorption site by a photon on optical imaging only becomes appreciable when the size of the inhomogeneity reaches about ten times of the transport mean free path or larger in human tissues. The theoretical formalism and computer algorithm for 3D tomographic image reconstruction shows with simulated data the potential to provide fast 3D images of the scattering and absorption objects at various depths in turbid media.

Available in PDF, EPUB and Kindle. Book excerpt: This book watches out for the issues on making moves for chest radiology in carcinoma of the chest. It focuses on all parts of radiological approaches to manage the breast illness, be it light (optical), sound (ultrasound), interest, microwave, electrical impedance, blend of these modalities, and a section of the incredibly intense issues on computer-aided detection. The dedication of the eminent analysts in this book has incorporated a lot of energy for the people who are adequately drawn in with the clinical organization of this ailment and also for the students of radiology and surgery alike. This book will definitely be appreciated and well taken by the surgeons, radiologists, and other professionals involved in this field. The contributions are excellent in terms of diagnostic approach by radiological means and would certainly be a step forward in making it possible to reach to a conclusive diagnosis of breast cancer much before it becomes inoperable. The chapters included will further our knowledge and to the best of my belief will make things easier and definable in terms of diagnosis of breast cancer.
Download or read book Functional Imaging of Early Markers of Disease written by N. Simpson and published by IOS Press. This book was released on 2004 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the second part which highlights the role that various imaging techniques play and/or might be able to play in detecting markers of disease. Cancer is often used as the example disease, but tumors exhibit many properties in common with other tissue, so it is possible to see how the techniques could be used in the diagnosis and management of other disease. There are also examples of the reverse of this flow of hypothesis and knowledge from one discipline to another. Magnetic resonance spectroscopy can be used to detect the chemical milieu of the nucleus being focused on, be it phosphorus-31 (Arias-Mendoza) or protons (He). Phosphorus is intimately involved in carbohydrate, phospholipid metabolism and energy transfer. The brain has been the testing ground for ideas in MRI and MRS; it continues to be so today, with extension to tumor diagnosis as insights are reached and assimilated. This issue contains three techniques that rely solely or partially on optical characteristics of tissue. The supplement, in 2 issues, has mostly emphasized possibilities rather than clinically available techniques.The final chapter attempts to draw together the modalities of medical imaging and push the frontiers yet further to show how imaging and markers can be used together in the screening, diagnosis, and management of patients' disease.

Download or read book X Ray Phase Contrast Tomography written by Luca Brombal and published by Springer Nature. This book was released on 2020-11-16 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: X-ray imaging is a corner stone of breast cancer diagnosis. By exploiting the phase shift of X-rays rather than their attenuation, phase-contrast tomography has the potential to dramatically increase the visibility of small and low contrast features, thus leading to better diagnosis. This thesis presents research on the first synchrotron-based project developing a clinical phase-contrast breast computed tomography (CT) setup at Elettra, the Italian Syncrotron Radiation Facility. This book includes a comprehensive theoretical background on propagation-based phase-contrast imaging, exploring and extending the most recent image formation models. Along with theory, many practical implementation and optimization issues, ranging from detector-specific processing to setup geometry, are tackled on the basis of a large number of experimental evidences. Most of the modelling results and data analysis have general validity, being a valuable framework for optimization of phase-contrast setups. Results obtained at synchrotron are also compared with "real world" laboratory sources: both a first-of-its-kind comparison with one of the few hospital breast CT systems and a state-of-the-art implementation of monochromatic phase-contrast micro-tomography with a conventional rotating anode source are presented. On a more general level, this work sheds a light on the importance of synchrotron-based clinical programs, which are key to trigger the long-anticipated transition of phase-contrast imaging from synchrotrons to hospitals.
