Download or read book Bone Quantitative Ultrasound written by Pascal Laugier and published by Springer Nature. This book was released on 2022-05-05 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many significant achievements in new ultrasound technologies to measure bone and models to elucidate the interaction and the propagation of ultrasonic waves in complex bone structures have been reported over the past ten years. Impaired bone remodeling affects not only the trabecular compartment but also the cortical one. Despite the crucial contribution of the cortical structure to the whole bone mechanical competence, cortical bone was understudied for a long time. A paradigm shift occurred around 2010, with a special focus placed on the importance of cortical bone. This has sparkled a great deal of interest in new ultrasound techniques to assess cortical bone. While our book ‘Bone Quantitative Ultrasound’ published in 2011 emphasized techniques to measure trabecular bone, this new book is devoted for a large part to the technologies introduced recently to measure cortical bone. These include resonant ultrasound spectroscopy, guided waves, scattering, and pulse-echo and tomography imaging techniques. Instrumentation, signal processing techniques and models used are detailed. Importantly, the data accumulated in recent years such as anisotropic stiffness, elastic engineering moduli, compression and shear wave speeds of cortical bones from various skeletal sites are presented comprehensively. A few chapters deal with the recent developments achieved in quantitative ultrasound of trabecular bone. These include (i) scattering-based approaches and their application to measure skeletal sites such as the spine and proximal femur and (ii) approaches exploiting the poro-elastic nature of bone. While bone fragility and osteoporosis are still the main motivation for developing bone QUS, this Book also includes chapters reporting ultrasound techniques developed for other applications of high interest such as 3-D imaging of the spine, assessment of implant stability and transcranial brain imaging. This book, together with the book ‘Bone Quantitative Ultrasound’ published in 2011 will provide a comprehensive overview of the methods and principles used in bone quantitative ultrasound and will be a benchmark for all novice or experienced researchers in the field. The book will offer recent experimental results and theoretical concepts developed so far and would be intended for researchers, graduate or undergraduate students, engineers, and clinicians who are involved in the field. The book should be considered as a complement to the first book publisher in 2011, rather than a second edition, in the sense that basic notions already presented in the first book are not repeated.
Download or read book Quantitative Ultrasound and Photoacoustic Imaging for the Assessment of Vascular Parameters written by Kristen M. Meiburger and published by Springer. This book was released on 2016-11-21 with total page 115 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the development of quantitative techniques for ultrasound and photoacoustic imaging in the assessment of architectural and vascular parameters. It presents morphological vascular research based on the development of quantitative imaging techniques for the use of clinical B-mode ultrasound images, and preclinical architectural vascular investigations on quantitative imaging techniques for ultrasounds and photoacoustics. The book is divided into two main parts, the first of which focuses on the development and validation of quantitative techniques for the assessment of vascular morphological parameters that can be extracted from B-mode ultrasound longitudinal images of the common carotid artery. In turn, the second part highlights quantitative imaging techniques for assessing the architectural parameters of vasculature that can be extracted from 3D volumes, using both contrast-enhanced ultrasound (CEUS) imaging and photoacoustic imaging without the addition of any contrast agent. Sharing and summarizing the outcomes of this important research, the book will be of interest to a broad range of researchers and practitioners in the fields of medical imaging and biomedical engineering.
Download or read book Quantitative Imaging with Mechanical Waves written by Peter Edward Huthwaite and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Quantitative imaging complements structural imaging by providing quantitative estimations of subsurface material properties as opposed to the sizes, shapes and positions of scatterers available from structural methods. The ability to reconstruct material properties from a series of wave measurements is extremely valuable in a range of applications as it potentially allows diagnostic technology with superior sensitivity and selectivity. Breast cancer, for example, is stiffer and hence of higher sound velocity than the surrounding tissue, so reconstructing velocity from ultrasonic measurements could allow cancer detection. Using this concept, breast ultrasound tomography has the potential to significantly improve the cost, safety and reliability of breast cancer screening and diagnosis over mammography, the gold- standard. Key to unlocking this potential is the availability of an accurate, fast, robust and high-resolution algorithm to reconstruct wave velocity. This thesis introduces HARBUT, the Hybrid Algorithm for Robust Breast Ultrasound Tomography, a new imaging approach combining the complementary strengths of low resolution bent-ray tomography and high resolution diffraction tomography. HARBUT's theoretical foundation is explained and applied to simulated and experimental, in-vivo, breast ultrasound tomography data, confirming that it generates a step change in image quality over existing techniques, revealing lesions that would not be visible on 'a mammogram. This thesis also shows how, by combining data from many slices, the out-of-plane resolution can be significantly improved compared to treating each slice independently. HARBUT is applied to alternative problems including guided wave tomography, which aims to quantify the remaining wall thickness of a potentially corroded, inaccessible plate-like structure. Thickness estimates within Imm for a lOmm nominal thickness plate were demonstrated for both simulated and experimental data. The thesis finally investigates HARBUT's performance with limited view configurations, and introduces VISCIT, the Virtual Image Space Component Iterative Technique, which accounts for the missing data, significantly improving the reconstructed image.

Download or read book Non contact Ultrasound written by Xiang Zhang (Ph. D.) and published by . This book was released on 2019 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis explores the design, development, and evaluation of two novel non-contact ultrasound imaging methods: immersion ultrasound and optical ultrasound. Immersion ultrasound utilizes traditional piezoelectric elements in a tomographic framework to develop new algorithms and acquisition methods for quantification of tissue geometry and properties in human proximal limbs. Bone is uniquely challenging for ultrasound due to the high impedance mismatch between bone and soft-tissue in the imaging domain. New imaging algorithms are necessary for both geometric and quantitative reconstruction of subjects with bone. Multiple immersion systems were designed and constructed using the framework presented in this thesis. Mechanical systems include a 4 degrees of freedom single element system and a fully flexible 36 degrees of freedom robotic system abbreviated MEDUSA (Mechanically Discrete Ultrasound Scanning Apparatus). An adaptive beamforming algorithm addressing specularity of bone in pulse-echo imaging and a Full Waveform Inversion algorithm for quantitative imaging with bone are discussed, with imaging results on tissue mimicking phantoms, excised animal tissue, and human subjects. Furthermore, a laser ultrasound (LUS) system was developed for full non-contact ultrasound imaging. LUS completely replaces conventional piezoelectric elements for generation and detection of ultrasound in biological tissue. LUS generates ultrasonic waves at the tissue surface via rapid transduction of optical energy to acoustic energy through thermomechanical coupling on the tissue surface and detects returning ultrasonic waves on the tissue surface using laser interferometry. In combination, LUS can utilize any tissue surface as a viable acoustic transmitter or detector. Analysis of light and tissue interactions presented in this thesis identifies the critical process parameters for soft-tissue imaging at eye and skin safe optical exposure levels. LUS system design methods and imaging results on tissue mimicking phantoms, excised tissue, and humans subjects are presented. Human LUS results marks the first instance of full non-contact optical ultrasound imaging of in-vivo human subjects. All systems presented in this thesis were calibrated to ensure safe optical and acoustic exposure levels for human subjects. Approval was obtained from the MIT Committee on the Use of Humans as Experimental Subjects (COUHES) prior to any human experimentation.

Download or read book Bone Quantitative Ultrasound written by Pascal Laugier and published by Springer. This book was released on 2010-12-01 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quantitative ultrasound (QUS) of bone is a relatively recent research field. The research community is steadily growing, with interdisciplinary branches in acoustics, medical imaging, biomechanics, biomedical engineering, applied mathematics, bone biology and clinical sciences, resulting in significant achievements in new ultrasound technologies to measure bone, as well as models to elucidate the interaction and the propagation of ultrasonic wave in complex bone structures. Hundreds of articles published in specialists journals are accessible from the Web and from electronic libraries. However, no compilation and synthesis of the most recent and significant research exist. The only book on QUS of bone has been published in 1999 at a time when the propagation mechanisms of ultrasound in bone were still largely unknown and the technology was immature. The research community has now reached a critical size, special sessions are organized in major international meetings (e.g., at the World Congress of Biomechanics, the annual meetings of the Acoustical Society of America, International Bone Densitometry Workshop, etc...). Consequently, the time has come for a completely up to date, comprehensive review of the topic. The book will offer the most recent experimental results and theoretical concepts developed so far and is intended for researchers, graduate or undergraduate students, engineers, and clinicians who are involved in the field. The central part of the book covers the physics of ultrasound propagation in bone. Our goal is to give the reader an extensive view of the mathematical and numerical models as an aid to understand the QUS potential and the types of variables that can be determined by QUS in order to characterize bone strength. The propagation of sound in bone is still subject of intensive research. Different models have been proposed (for example, the Biot theory of poroelasticity and the theory of scattering have been used to describe wave propagation in cancellous bone, whereas propagation in cortical bone falls in the scope of guided waves theories). An extensive review of the models has not been published so far. We intend in this book to present in details the models that are used to solve the direct problem and strategies that are currently developed to address the inverse problem. This will include analytical theories and numerical approaches that have grown exponentially in recent years. Most recent experimental findings and technological developments will also be comprehensively reviewed.
