Ultrasonic Scattering in Biological Tissues contains 14 chapters written by world-renowned authorities who describe current work related to theoretical and experimental aspects of ultrasonic scattering phenomenon in biological tissues. Introductory material regarding ultrasonic scattering in biological tissues is presented, followed by discussions on theoretical treatments, experimental approaches, in vitro results on selective tissues, in vivo results on various tissues, and the current status of quantitative backscatter imaging. Ultrasonic Scattering in Biological Tissues will be an excellent reference for biomedical engineers, ultrasound specialists, biophysicists, and radiology researchers.

Methods and Phenomena, 3: Ultrasound: Its Applications in Medicine and Biology, Part II focuses on the applications of ultrasound in biology and medicine, including irradiation, acoustic attenuation, and impedance distribution. The selection first tackles selected non-thermal mechanisms of interaction of ultrasound and biological media, therapy with continuous wave ultrasound, and pulse echo visualization. Discussions focus on imaging properties, modes of operation, rationale for selecting ultrasound as a therapeutic agent, mechanical disarrangement of tissue structures, and wave distortion. The manuscript then examines a research approach to visualization of breast tumors by ultrasound methods, acoustic characterization of tissue at the microscopic level, and intense focused ultrasound. Concerns cover systems for irradiation with intense focused ultrasound, interaction of intense focused ultrasound and biological tissue, sonomicroscopic characterization of tissues, acoustic attenuation and impedance distribution, velocity of sound distribution, and methods of procedure. The book tackles cavitation and its effects on organized mammalian tissues and thermal mechanisms in ultrasound-tissue interactions. The selection is a valuable source of data for researchers interested in the applications of ultrasound in biology and medicine.

The second E. C. Workshop on Ultrasonic Tissue Characterization was organized for the assessment of research goals and plans as the basis to a grant proposal for a "Concerted Action" which will be forwarded to the European Commission. It should, therefore, not only be considered as a work in progress exhibition which succeeded the former activities within the E. C. (Inventory on Tissue Characterization in Europe and first Workshop). The Steering Group invited a 1 imited group of Institutes to send its group leader and a research fel low in the entitled field, who should expose the overall research program, as wei 1 as the more specific work on tissue characterization by RF signal analysis and spectroscopy. The ultimate goal of the Workshop has been the formulation of schemes of interaction among the Institutes and individuals and the definition of cooperative research programs. The remainder of the groups and some of the groups present are working in the field of analysis and processing of cl inical A- and B-mode echograms (i. e. video signals). Because this work is more closely related to the cl inical diagnostics it was decided that for that reason no preparatory workshop was needed. In the final proposal for the Concerted Action this work wi 1 1 get ample attention. Although not many clinicians were present, their positive interest in the sophisticated analysis techniques and their contribution to the dis cussions again have been a most valuable and stimulating experience.
