Diffuse Optical Tomography: Principles and Applications 1st Edition (2010) by Huabei Jiang PDF
Ebook Info
- Published: 2010
- Number of pages: 376 pages
- Format: PDF
- File Size: 18.05 MB
- Authors: Huabei Jiang
Description
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 imagingJoint imaging to treat progressive diseases such as arthritisMonitoring of tumor responseNew contrast mechanisms and multimodality methodsThis 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.

Digital Image Processing for Ophthalmology: Detection of the Optic Nerve Head (Synthesis Lectures on Biomedical Engineering) 1st Edition (2011) by Xiaolu Zhu PDF
Ebook Info
- Published: 2011

- Format: PDF
- File Size: 1.52 MB
- Authors: Xiaolu Zhu
Description
Fundus images of the retina are color images of the eye taken by specially designed digital cameras. Ophthalmologists rely on fundus images to diagnose various diseases that affect the eye, such as diabetic retinopathy and retinopathy of prematurity. A crucial preliminary step in the analysis of retinal images is the identification and localization of important anatomical structures, such as the optic nerve head (ONH), the macula, and the major vascular arcades. Identification of the ONH is an important initial step in the detection and analysis of the anatomical structures and pathological features in the retina. Different types of retinal pathology may be detected and analyzed via the application of appropriately designed techniques of digital image processing and pattern recognition. Computer-aided analysis of retinal images has the potential to facilitate quantitative and objective analysis of retinal lesions and abnormalities. Accurate identification and localization of retinal features and lesions could contribute to improved diagnosis, treatment, and management of retinopathy. This book presents an introduction to diagnostic imaging of the retina and an overview of image processing techniques for ophthalmology. In particular, digital image processing algorithms and pattern analysis techniques for the detection of the ONH are described. In fundus images, the ONH usually appears as a bright region, white or yellow in color, and is indicated as the convergent area of the network of blood vessels. Use of the geometrical and intensity characteristics of the ONH, as well as the property that the ONH represents the location of entrance of the blood vessels and the optic nerve into the retina, is demonstrated in developing the methods. The image processing techniques described in the book include morphological filters for preprocessing fundus images, filters for edge detection, the Hough transform for the detection of lines and circles, Gabor filters to detect the blood vessels, and phase portrait analysis for the detection of convergent or node-like patterns. Illustrations of application of the methods to fundus images from two publicly available databases are presented, in terms of locating the center and the boundary of the ONH. Methods for quantitative evaluation of the results of detection of the ONH using measures of overlap and free-response receiver operating characteristics are also described.

Description
Digital retinal imaging performed by primary care providers and nurses, followed by remote image interpretation (teleretinal imaging), is rapidly acquiring a crucial role in many parts of the world as it permits the detection of major diseases, such as diabetic retinopathy and glaucoma, in patients who would otherwise be beyond the reach of a trained ophthalmologist. In this book, experts from around the world describe how digital teleretinal screening can be set up and optimally utilized. Technical issues are discussed, and the appropriate use of screening for different diseases and in different age groups is explained. The major part of the book draws upon the clinical experience of leading practitioners in a wide range of teleretinal applications. The result is a comprehensive source of high-quality information for clinicians and other health professionals who are involved in eye care delivery, so that they can assess how teleretinal screening might be applied to their working practice.

⭐I heard Ivan Schuab MD lecture in Kansas City at the KCO&O and heard about this book. It is a good reference for common and uncommon eye-skin diseases. Identify uncommon diseases and may help treat insomnia.
⭐There are a lot of unusual diseases in this book. At least, unusual to the ophthalmologist. In other words, the focus seems to be on dermatologic disorders that may have ocular findings rather than ophthalmologic disorders that may have integumentary findings. That is part of what makes this book great for ophthalmologists.The text is well written, but as it is with most books like this, the key features of a diseases are not emphasized as compared to a laundry list of findings. Also, little discussion exists on treatment. The chapter organization is good and the chapters are not overly long. The pictures, in general, are very good. However, there are a number of diseases in this “ATLAS” with no associated picture. And, the organization of the pictures is a little weird.But, overall, I do recommend this book for ophthalmologists interested in rare diseases or “systemic disease.” This book complements the kanski book on systemic disease and the one by Weingeist.
⭐Good photos! Good atlas!

Ebook Info
- Published: 2014
- Number of pages: 131 pages
- Format: PDF
- File Size: 3.7 MB
- Authors: Aniz Girach
Description
This clinically oriented book is the first to be devoted wholly to the diagnosis and treatment of vitreo-macular interface disease, characterized by a combination of vitreo-macular adhesion (VMA) and vitreo-macular traction (VMT) that is implicated in a variety of disorders. World-renowned experts in the field discuss epidemiologic, anatomic, and physiologic aspects, document the findings obtained with newer imaging techniques, such as spectral domain optical coherence tomography, describe the treatment options, and report on the results of preclinical and clinical trials, including some previously unpublished findings. This book will prove invaluable for ophthalmologists as we advance toward a future in which treatments of diseases such as age-related macular degeneration and diabetic retinopathy will likely require adjunctive therapy to tackle VMA/VMT concurrently.
