This volume contains the proceedings of the Tenth International Symposium on Acoustical Imaging held in Cannes, France, October 12th through the 16th, 1980. Fifty-seven papers were presented over the course of the four day meeting. Fifty-two manuscripts were received in time for publication of the proceedings. There was representation from 14 nations, including England, France, U.S.A., West Germany, Canada, Italy, Japan, Poland, The Netherlands and Norway among the authors and in addition, Switzerland, Spain, Belgium, and Denmark were represented. The following papers were presented at the meeting for which manuscripts were not received in time for publication: "Improved Phased Array Imaging and Medical Diagnosis" by F.L. Thurstone; "Scanning Acoustic Microscope Operating in the Reflection Mode" by H. Kanda, I. Ishikawa, T. Kondo, and K. Katakura; "Empirical Determination of Flaw Characteristics Using the Scanning Laser Acoustic Microscope - SLAM" by D. Yuhes, C.L. Forres, and L.W. Kessler; "A Wide Angled Fraction Limited Holographic Lens System for Acoustical Imaging" by H. Heier; "Progress in the Development of Sonographic Contrast Agents" by J. Ophir, and F. Maklad, A. Gobuty and R.E. McWhirt.
