Download or read book Acoustical Imaging written by Roman Gr. Maev and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 510 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book constitutes the Proceedings of the 26th Symposium on Acoustical Imaging held inWindsor, Ontario, Canada during September 9-12, 2001. This traditional scientific event is recognized as a premier forum for the presentation of advanced research results in both theoretical and experimental development. The lAIS was conceived at a 1967Acoustical Holography meeting in the USA. Since then, these traditional symposia provide an opportunity for specialists who are working in this area to make new acquaintances, renew old friendships and present recent results of their research. Our Symposium has grown significantly in size due to a broad interest in various topics and to the quality of the presentations. For the firsttime in 40 years, the IAIS was held in the province of Ontario in Windsor, Canada's Automotive Capital and City of Roses. The 26th IAIS attracted over 100specialists from 13countries representing this interdisciplinary field in physical acoustics, image processing, applied mathematics, solid-state physics, biology and medicine, industrial applications and quality control technologies. The 26th lAIS was organized in the traditional way with only one addition-a Special Session "History of Acoustical Imaging" with the involvement of such well known scientists as Andrew Briggs, Noriyoshi Chubachi, Robert Green Jr., Joie Jones, Kenneth Erikson, and Bernhard Tittmann. Many of these speakers are well known scientists in their fields and we would like to thank them for making this session extremely successful.

Available in PDF, EPUB and Kindle. Book excerpt: The present volume on basic physics of ultrasonographic imaging procedures provides clear and concise information on the physics behind ultrasound examinations in diagnostic imaging. It attempts to present the subject from a simple approach that should make it possible for the target groups to comprehend the important concepts which form the physical basis of ultrasonic imaging. The main target group of this manual is radiological technologists and radiographers working with diagnostic ultrasound in developing countries. Clinicians and nurse practitioners may also find the simple presentation appealing. A conscious effort has been made to avoid detailed mathematical treatment of the subject. The emphasis is on simplicity.

Download or read book Sound Speed Estimation and Phase aberration Correction for Medical Ultrasound Imaging written by Rehman Ali and published by . This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Pulse-echo ultrasound imaging is a medical imaging modality that constructs images based on the back-scatter of acoustic waves in tissue. Most ultrasound systems assume a spatially constant speed of sound when the time-of-flight of the acoustic wave is used to focus these back-scattered signals into medical images. However, the speed of sound in human tissue can vary spatially by tissue type and composition. The primary focus of this thesis is the estimation of a spatially-varying speed of sound in the tissue and using this speed of sound in order to optimally focus ultrasound signals into images, effectively correcting for phase aberrations resulting from an erroneous speed of sound during the focusing. We first develop a retrospective encoding and decoding scheme that enables us to reconstruct a multistatic synthetic aperture dataset from an arbitrary sequence of transmissions. The regularized inversion technique for the recovery of the multistatic dataset achieves a 99.36\% correlation between the multistatic dataset recovered from a walking-aperture focused-transmit sequence and the ground-truth. This technique is used to successfully demonstrate sound speed estimation and distributed aberration correction in abdominally-layered media. For sound speed estimation in layered media, the root mean-square error in simulations of two-layer media is 4.6 and 2.5 m/s at 4 and 8 MHz transmit frequency, respectively. These sound speed estimates are then used to optimally focus the multistatic synthetic aperture and achieve distributed aberration corrections. In phantom experiments, point target resolution improves from 0.58 to 0.26 and 0.27 mm, and lesion contrast improves from 17.7 to 23.5 and 25.9 dB, as a result of distributed aberration correction using the eikonal and wave-field correlation techniques, respectively. Then, we explore modeling and inversion techniques from ultrasound transmission tomography and seismic imaging, which we apply to pulse-echo ultrasound imaging. We demonstrate that shot-profile migration from seismic imaging can be used as a generalized synthetic aperture imaging technique for pulse-echo ultrasound imaging where it yields a 55\% improvement in point target resolution and 8.6 dB improvement in contrast over virtual source synthetic aperture. Shot-profile migration also lays the groundwork for an initial implementation of wave-equation migration velocity analysis (WEMVA) for pulse-echo ultrasound imaging. The complete investigation of WEMVA in pulse-echo ultrasound is left to future work.

Download or read book Ultrasonic Tissue Characterization written by Floyd Dunn and published by Springer Science & Business Media. This book was released on 2013-12-18 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are two major reasons for having this symposium. First, Tohoku Univer sity is the place where ultrasound investigations in Japan originated. Starting from the research studies of Professors H. Nukiyama and Y. Kikuchi of To hoku University, Professor J. Saneyoshi of Tokyo Institute of Technology, and Dr. K. Kato of Osaka University - all graduates of Tohoku University - the results spread to all parts of Japan. More recently we have had acoustic macro scopic studies by researchers like Professor N. Chubachi. As regards tissue char acterization, which was the main theme of the symposium, the collaboration among research workers in Japan and the United States started 10 years ago between Professor F. Dunn of the University of Illinois and staff members of Tohoku University and the Tokyo Institute of Technology. So this conference commemorates the lOth anniversary of that joint research effort. The second reason for this conference is that the application of ultrasound has become wide spread and indispensable in the routine clinical activities of medicine. But there have not been many breakthroughs in terms of quantitative and qualitative measurement of the living body tissues. Also, there are many problems with regard to practical application. There are various points that have not been elucidated yet as to the physical and acoustical characteristics of ultrasound itself. The methodology has not in all cases been well established. Therefore, the scientific elucidation of these areas is essential.
