Stroke G. et al. (eds.) Ultrasonic Imaging and Holography: Medical, Sonar, and Optical Applications

Plenum Press, 1974. — 644 p.This book contains the complete set of papers presented at the Third United States-Japan Science Cooperation Seminar on the Subject of Holographic Imaging and Infor­mation Processing, held at Hawaii, January 8 to 13, 1973, under the joint sponsorship of the National Science Foun­dation and the Japan Society for the Promotion of Science. The papers present the latest advances and state of the art in areas ranging from ultrasonic holography, radar and sonar to ultrasonic pulse-echo imaging, acoustic microscopy and image processing in biomedical engineering. Computer processing of ultrasonic images is extensively discussed. Several papers describe the remarkable appli­cations of ultrasonics in medical diagnostics. One describes new features in R&D management that are particularly relevant to the field as a result of recent changes in national science and technology policies. We also present the most recent advances in the powerful methods of image improvement (sharpening, deblurring) which have been made possible with the aid of holograms used as computing elements; the holographic image deblurring method is capable of an astonishing improvement of images that are still unattainable with even the most powerful digital computer methods.
