5 PREFACE Due to the ever increasing interest in the use of non-invasive ultrasonic methods in medical diagnostics on the one hand and the specific effects of ultrasound in medical therapy on the other, the questions of safety and optimal applications are topical and of great importance. For this reason the symposium "Ultrasound Interaction in Biology and Medicine," initiated and supported by the "International Organization of Medical Physics," took place. The organizers were the Institute of Applied Biophysics of the Martin-Luther-University, Halle (Saale), German Democratic Republic, in association with the Society for Physical and Mathematical Biology of the GDR along with other scientific organizations. Renowned and internationally noted specialists in the field of ultrasonics reported on the latest findings regarding the biological interaction of ultrasound, which promised future improvements in the methods of ultrasonic diagnostics and gave and up-to-date insight into the biological effectiveness of ultrasound. We are pleased to be able to publish selected contributions to this symposium collected in one volume. The methods of investigation, theoretical considerations and results concerning the interaction of ultrasound on molecular, cellular and system levels contained herein will remain up-to-date for a long time to come, providing thought provoking material for further inter-disciplinary basic research and medical application.

9 WELCOME ADDRESS The International Organization for Medical Physics was started to improve international communication between physical scientists throughout the world, who use their "know-how" to improve health care and medical techniques. So far, it has called six major international conferences, during which the worldwide gathering of delegates has discussed and learned of work covering the whole field of medical physics. The Council decided recently that, in addition, it wished to sponsor smaller, more specialized symposia devoted to one carefully selected topic. This meeting is the first one to be sponsored by IOMP in accordance with this policy. IO~ hopes that this gathering together at Reinhardsbrunn of highly qualified researchers to discuss "Ultrasound Interaction in Biology and Medicine" will prove to be of unique significance in the development of this subject, and hopes that the interchange of information will give a forward boost to your knowledge which may, in turn, help the sick wherever they are. IOMP congratulates all those who have initiated this meeting, all those who have made the excellent preparations, and wishes it every success. Prof. Dr. I.R. Mallard President of the International Organization of Medical Physics xiii
