内容説明
This volume contains the Proceedings of the Fifth International Symposium on Acoustical Holograhy and Imaging, held in Palo Alto, California, on July 18-20, 1973. The title of this Symposium differed from that of the previous four by the addition of the word "Imaging," reflecting an increase in emphasis on nonholographic methods of acoustical visualization. For convenience, no change has been made in the title of this published series. The 42 Symposium papers cover a wide range of theoreti- cal and applied topics, and effectively define the state-of- the-art in this rapidly developing field. Many of them relate to applications of acoustic visualization in such diverse fields as nondestructive testing, medical diagnosis, microscopy, underwater viewing, and seismic mapping. The papers presented at the Symposium were selected with considerable assistance from the Program Committee. The Editor wishes to thank the following persons for serving as members of this committee: P. Alais, University of Paris, France; B. A. Auld, Stanford University; D. R. Holbrooke, Children's Hospital of San Francisco; A. Korpel, Zenith Radio Corporation; J. L. Kreuzer, Perkin Elmer Corporation; A. F.

This volume contains the Proceedings of the Sixth International Symposium on Acoustical Holography and Imaging, held in San Diego, California, February 4-7, 1975. The title of this symposium differs from that of the first four by the addition of the word "Imaging", reflecting an increase in emphasis on nonholographic methods of acoustical visualization. For convenience, no change has been made in the title of this published series. The 38 papers presented here define the state-of-the-art in the rapidly developing field of acoustical holography and imaging. Many of them describe applications in such fields as medical diagnostics, microscopy, nondestructive testing, underwater viewing, and seismology. The Editor recognizes the diligent efforts of the authors in advancing the technology of Acoustical Imaging and thanks them for preparing and submitting descriptions of their work. The papers were selected with the able assistance of the Program Committee that con- sisted of P.S. Green, Stanford Research Institute; J.F. Havlice, Stanford Microwave Laboratory; B.P. Hildebrand, Battelle Northwest; D.R. Holbrooke, Children's Hospital of San Francisco; P.N.
Keating, Bendix Research Laboratories; A. Korpel, Zenith Radio Corporation; B.J. McKinley, Lawrence Livermore Laboratory; A.F. Metherell, University of Miami; J. Powers, Naval Postgraduate School; and F.L. Thurstone, Duke University. The Editor appreciates the help of the session chairmen: D.R. Holbrooke, Children's Hospital of San Francisco; Mahfuz Ahmed, Zenith Radio Corporation; R.K. Mueller, University of Minnesota; G. Wade, University of California at Santa Barbara; B.P.

内容説明
This volume contains the papers presented at the Seventh International Symposium on Acoustical Imaging and Holography. The meeting was held in Chicago, Illinois U.S.A. on August 30 - September 1, 1976. Since 1967 this series of conferences has served as an international forum for bringing together the many different facets of the ultrasonic visualization field. Medical diagnosis, nondestructive testing, underwater viewing, seismic the mapping, and acoustic analytical microscopy are examples of broad range applications of this technology. Throughly broad in scope, the common denominator that binds this volume together is the application of engineering and physics disciplines to the creation of images by means of ultrasonic waves. Efforts on the part of the program committe and their institutions are greatly appreciated, They are acknowledged below: Newell Booth Nave lex Arlington, Va. Byron B. Brendan Holosonics, Inc.
