Doody's Review ServiceReviewer: William J Davros, PhD, ABMP (D)(Cleveland Clinic Foundation)
Description: This book covers the core electrical signal processing commonalities of four broad classes of medical imaging devices: x-ray and CT, flat panel detectors, SPECT and PET systems, ultrasound imaging and MRI. It is well illustrated with many gray-shaded photographs, a wealth of figures and graphs, and plenty of equations for those who enjoy a deeper understanding of signal processing as it relates to imaging.
Purpose: The purpose is to introduce readers to the common aspects of signal processing in medical imaging. The editor has collected chapters from an international list of authors. The book's four parts are tied together by the common issues of signal collection, processing, noise rejection, and image formation.
Audience: It is clearly aimed at electrical engineers, biomedical engineers, signal processing engineers, and to some extent medical physicists. It also would be appropriate for graduate students in these disciplines who have an interest in the mathematical and circuits elements of signal handling aspects in medical imaging. Much of the book has mathematical equations that are calculus or linear algebra based, so readers should be well versed in intermediate mathematics. It is not appropriate as a general primer in medical imaging and would not be useful for radiology residents or undergraduates.
Features: Part one is dedicated to x-ray and x-ray computed tomography imaging and is composed of four chapters. The chapter on x-ray and computed tomography imaging principles is a bit lacking in content and does not fit well with the other three chapters, which are well executed discussions of active matrix flat panel imagers, circuits for digital x-ray imaging, and noise coupling in digital x-ray imaging. Each is loaded with illustrations, charts, graphs, and mathematical equations that are useful without being overbearing. Part two on imaging in nuclear medicine has two chapters that describe SPECT and PET imaging and low noise electronics. The first chapter is a nicely laid out review of the basics of nuclear medicine imaging that is clearly written, well organized, and has tables that are particularly useful in codifying the most used radio tracers and nuclear imaging exams. The second chapter is a tightly written thesis on radiation detection and sensing using low noise electronics. It is highly technical, loaded with mathematical formulations, a wealth of circuit diagrams, and nuances regarding the roles they play in pulse shaping. Part three is a single long, wonderfully constructed chapter on medical ultrasound that starts off with easy-to-understand concepts and builds into a more detailed analysis of each stage of ultrasound imaging. This chapter includes superb quality illustrations. Equations and circuit diagrams are used sparingly and are well supported by the text. This is one of the strongest and most cohesive chapters in the book. Part four consists of two chapters on magnetic resonance imaging. The first is nicely written, thoughtfully constructed, easy to read and follow, and has higher level of detail on the mathematics of MRI than is customarily seen. Sadly, the chapter that follows is much weaker in comparison. It is short, poorly structured, and adds little to the topic. The index is underdeveloped but this is somewhat mitigated by extensive reverence bibliographies in the back of each chapter.
Assessment: This book is written for readers who seek a deeper understanding of the electronics, circuits design theory, and mathematics of medical imaging. A few chapters meet that objective. On the whole, the book does not hang together as a cohesive work but instead seems to be a loose compilation of chapters whose quality, integration, and content vary widely. Readers should be well versed in circuit design theory, calculus, and to a lesser extent differential equations, to fully grasp the concepts in parts of this book.
