Imaging Sound


Book Description

The rulers of the Mughal Empire of India, who reigned from 1526 to 1858, spared no expense as patrons of the arts, particularly painting and music. They left as their legacy an extraordinarily rich body of commissioned artistic projects including illustrated manuscripts and miniature paintings that represent musical instruments, portraits of musicians, and the compositions of ensembles. These images form the basis of Bonnie C. Wade's study of how musicians of Hindustan encountered and Indianized music from the Persian cultural sphere. Imaging Sound is a contribution to many fields in its unique combination of sources and methods: it is the study of musical change; of image-making in the past and the methodological use of images as "texts" in the present; of the role of patronage in the Mughal Empire; and of the development of South Asian culture.




Imaging Sound


Book Description

The rulers of the Mughal Empire of India, who reigned from 1526 to 1858, spared no expense as patrons of the arts, particularly painting and music. They left as their legacy an extraordinarily rich body of commissioned artistic projects including illustrated manuscripts and miniature paintings that represent musical instruments, portraits of musicians, and the compositions of ensembles. These images from the basis of Bonnie C. Wade's study of how musicians of Hindustan encountered and Indianized music from the Persian cultural sphere. Combining ethnomusicological and art historical methods with history and lore, Wade has written a truly interdisciplinary study of cultural life on the Indian subcontinent. Wade focuses first on Akbar, showing how political and cultural agendas intertwined in the portrayal of Mughal court life. She then follows the depictions of music-making through paintings of Akbar's successors, Jahangir and Shah Jahan, to trace the gradual synthesis of Persian and Indian culture. Because music of the period was not notated but was transmitted orally, Wade relies on this wealth of visual evidence to reconstruct the musical life of the Mughals and its relation to the Mughal political agenda. As a major untapped resource, these images suggest new interpretations of the history of the Mughal Empire -- including original ideas about the role of patrons in the production of the arts and, importantly, the role of women in Mughal court life -- that are confirmed and complemented by the written sources of the period. Imaging Sound is a contribution to many fields in its unique combination of sources and methods: it is the study of musical change; of image-making in the pastand the methodological use of images as "texts" in the present; of the role of patronage in the Mughal Empire; and of the development of South Asian culture. In her synthesis of music, literature, art, and culture, Wade deepens our knowledge of the manner in which the orally transmitted tradition of Hindustani music came to be what it is today. The book is beautifully illustrated with more than 180 reproductions of Mughal paintings and manuscripts. These rare images are the basis for a study that is fully immersed both in current intellectual debates and in three centuries of Mughal cultural life.




Medical Imaging Systems


Book Description

This open access book gives a complete and comprehensive introduction to the fields of medical imaging systems, as designed for a broad range of applications. The authors of the book first explain the foundations of system theory and image processing, before highlighting several modalities in a dedicated chapter. The initial focus is on modalities that are closely related to traditional camera systems such as endoscopy and microscopy. This is followed by more complex image formation processes: magnetic resonance imaging, X-ray projection imaging, computed tomography, X-ray phase-contrast imaging, nuclear imaging, ultrasound, and optical coherence tomography.




Acoustic Characterization of Contrast Agents for Medical Ultrasound Imaging


Book Description

"The book consists of nine chapters. The first 3 chapters give a broad overview of the acoustic theory for bubble-sound interaction, both linear and nonlinear. Most contrast agents are stabilized in a shell, and this shell can have a strong influence on the interaction between the bubbles and the ultrasound. The effect of the shell is given special attention, as this is not easily found in other bubble literature. Chapters 4, 5, 6 and 7 describe experimental and theoretical methods used to characterize the acoustic properties of the agents, and results of studies on some agents. Chapter 8 shows how the theory and the experimental results can be combined and used to model various phenomena by means of computer simulations. The main purpose of the simulations is to get insight into the mechanisms behind the described phenomena, not to get accurate predictions and values.




Acoustical Imaging


Book Description

The contents of this volume are the proceedings of the 23'd International Symposium on Acoustical Imaging which took place 13-16 April, 1997, in Boston, Massachusetts. The first Symposium met 25 years ago. Originally the Symposium met in California, then elsewhere within the United States but beginning in 1988 the Symposia began to meet outside of the United States as welL It is now being held about every eighteen months, alternately in the United States and then outside. The present pattern is to hold one meeting in East Asia, then in the USA, then in Europe and again in the USA However, for scheduling reasons the next Symposium will be in Santa Barbara, California, followed by England and then East Asia. It is to be noted that the Symposium is a free standing institution, not associated with any other organization. Each meeting is the total responsibility of its chairman with the advice of past chairmen. Papers are submitted in response to the call for them and reviewed by an International Scientific Advisory Board . . The quality depends entirely on the response to the calL It is gratifYing to note that the Symposium has attained the status that attracts high quality contributions despite (or perhaps because ot) the loose structure. Two factors that have appeal are that there is only one session and that there is time during the meeting for extensive discussion.




Acoustical Imaging


Book Description

Volume 15 follows the format of earlier volumes in the series. The contents give the next installment in the varied aspects of acoustical imaging research. On this occasion, some emphasis was placed on the rela tionship of l1nderwater acoustics to acoustical imaging and a volume of papers under the title "Underwater Acoustics Proceedings from the 12th ICA Symposium held in Halifax," will appear at roughly the same time as this volume. There is no duplication in these volumes but they are in terlinked, at least to the extent that papers from common conference sessions appear in one or another volume. An innovation is the review paper presented at the beginning of the volume "A History of Acoustical Imaging," by G Wade. This fairly detailed review comes at a point in time when so much has been achieved and in some cases passed by, that a record of some of the earlier work might help to keep a balance with the large collections of research papers which have appeared in the many volumes.




Acoustical Imaging


Book Description

This volume contains forty-one papers presented at the Eleventh International Symposium on Acoustical Imaging held on 4-7 Ma~ in Monterey, California. The objective of this conference series is to bring together workers in diverse areas and applications of Acoustical Imaging for interaction and exchange of ideas. People working in other aspects of scalar wave theory and applications also benefit from this series. The papers presented here demonstrate continued growth in the activity of this field. In this conference there was emphasis on New Techniques, Acoustic Tomography, Tissue Characterization, Signal Processing, Inversion Techniques, and Transducers and Arrays. The success and stimulation of the conference and of the papers presented in this volume is owed, of course to the authors and participants. Many thanks are due to the authors and their co-workers for their diligence and enthusiasm in performing their research, preparing their manuscripts and presenting their results. The editor would like to express his appreciation to each and every one of them.




Acoustical Imaging


Book Description

The 17th International Symposium on Acoustical Imaging was held at Tohoku University, Sendai, Japan, during May 31-June 2, 1988. The symposium was organized by the ultrasonics research group of Tohoku University and the IEEE ijFFC Society, Tokyo Chapter. Of the 128 papers submitted, 88 were presented during the symposium, which comprised 144 researchers from 13 countries. This volume contains 81 papers as the record of the symposium and is clas sified into the following sections: (1) Acoustic Microscopy and its Applications; (2) Non-Destructive Evaluation; (3) Signal Processing of Images; (4) Acoustic Measurements and Physical Acoustics; (5) Medical Ultrasonic Diagnostics; (6) Acoustic Sensors; (7) Acoustic Holography and Tomography; (8) Seismic Exploration; and (9) Imaging Instrumentation and Other Techniques. A number of the papers submitted were associated with medical ultrasonic diagnostics and acoustic microscopy, reflecting a major activity in acousti cal imaging at Tohoku University. Accordingly, two invited talks were focused on this area: acoustic microscopy by Dr. G. A. D. Briggs of the University of Oxford and medical ultrasonics by Prof. M. Tanaka of Tohoku University. In light of the history of research in this field at our university, we are delighted to have had the opportunity to host the 17th symposium.
