  • Rather than focusing on earlier treatments, based largely on the simplifications of geometrical acoustics, Physical Principles of Medical Ultrasonics examines concepts of wave acoustics, introducing them in the very first chapter. Practical implications of these concepts are explored, first the generation and nature of acoustic fields, and then their formal descriptions and measurement. Real tissues attenuate and scatter ultrasound in ways that have interesting relationships to their physical chemistry, and the book includes coverage of these topics.

  • The subject of acoustic waves might easily be considered a mature one, quite specialized, with narrow and circumscribed fields of interest and of application. The present book is an evidence of the opposite: it witnesses how the concept of acoustic wave, a collective displacement of matter which perturbs an equilibrium configuration, is a pervasive concept, which emerges in very different fields. This type of phenomena can be analyzed from different points of view, it can be exploited in different ways, and is the object of active investigations.
