PREFACE
The formation of images by ultrasound is a fascinating
study, with well-established, yet rapidly growing, applic-
ations in medicine and with increasing relevance to a
surprisingly disparate set of problems in the non-destructive
examination of materials and components. The present
volume is a record of the research presented at the Twelfth
International Symposium on Acoustic Imaging, held in
London during July 1982. Whilst, therefore, it offers
primarily a snap-shot in time of a rapidly developing
field, it is so organized that it will also serve as a
high-speed entry into the literature for someone embarking,
for the first time, on· researches in this branch of applied
science.
As in previous volumes, some of the work reported is
concerned with topics which, whilst of critical importance
to the performance of any imaging system, - e.g. transducers,
signal processing may not address themselves to image
formation per se. A new departure is the inclusion
of photo-acoustic imaging a subject of rapidly growing
importance for many of the same application areas relevant
to acoustical imaging.
The editors, with the enthusiastic co-operation of the
Publishers, have aimed to achieve the highest possible
speed a publication date within four months of the
conference itself. In the pursuit of this endeavour,
it is not impossible that the density of typos, and other
minor errors which rt!main, is marginally higher than
could have been achieved, given a more leisurely editing
pace. The editors would like to express their sincere
thanks to Dr David Sinclair and Mrs Lee Surry who have
ensured nonetl1eless that a high standard of presentation
has been achieved. Their gratitude also extends to
all authors who, by careful attention to the "rules" of
camera-ready production, and by their prompt deli very

of the manuscrips, have played the key role in the creation
of this volume and in allowing us rapidly to present
it to the scientific community.
