The purpose of this book is to provide both an introduction and a state-of-the-art
review of the essential physics and signal processing principles of diagnostic ultrasound
in a single reference volume with a unified approach. This book draws together
many of the ideas from seminal papers, the author’s research, and other sources in a
single narrative and point of view. Unlike texts that present only the theory of acoustic
fundamentals, this book relates topics to each other in the context of ultrasound
imaging and practical application. It is the author’s hope that this work will contribute
to the overall development of ultrasound diagnostic imaging by serving as a focus
for discussion, an information source for newcomers, and a foundation for further
inquiry.
This text is intended for a graduate level course in diagnostic ultrasound imaging
and as a reference for practicing engineers in the field, medical physicists, clinicians,
researchers, design teams, and those who are beginning in medical ultrasound, as well
as those who would like to learn more about a particular aspect of the imaging
process. This book is an introduction to the basic physical processes and signal
processing of imaging systems, and as a guide to corresponding literature and terminology.
Parts of the book can be read on several levels, depending on the intent and
background of the reader. While this book provides sufficient equations for a scientific
foundation, there are also many parts of the book that go on for long stretches
without any equations. Equations can be thought of as a more precise description of
the variables involved and provide the means of simulation and deeper analysis.
This work is based in part on my nearly 20 years of research and development
experience at Hewlett Packard, later Agilent Technologies. Since my departure, the
healthcare group where I worked for nearly 20 years has become, by acquisition, part
of Philips Medical Ultrasound. I am indebted to my former colleagues for our many
collaborations over the years and for providing many requested images and material
for this book. Even though many of the images and system descriptions are from
Philips, readers can take some of this material to represent typical imaging systems.
Diagnostic ultrasound has been in use for over 50 years, yet it continues to evolve
at a surprisingly rapid rate. In this fragmented world of specialization, there is information
in abundance, but it is difficult to assimilate without order and emphasis. This
book strives to consolidate, organize, and communicate major ideas concisely, even
though this has been a challenging process. In addition, many essential pieces of
information and assumptions, known to those experienced in the field and not
available in journals and books, are included.
