Practical MR Physics Review

Practical MR Physics
Average Reviews:

(More customer reviews)
Practical MR Physics is an excellent addition to any department's library. The physics of MR are addressed in clear concise terms and presented in an understandable format. What really sets this text apart is the authors approach to imaging artifacts. Through real world case presentations, the readers are educated about the artifacts encountered, their underlying causation, and methods for elimination. I have added this book to my recommended reading list for MRI Students, and also recommend it as a valuable resource for practicing technologists.

The underlying physics of magnetic resonance imaging is a topic of considerable importance since a basic understanding is necessary to accurately interpret and generate high quality MR images.Yet it can be a challenging topic in spite of the best efforts of both teachers and students of the subject. Practical MR Physics reviews the basic principles of MR using familiar language and explains the causes of common imaging artifacts and pitfalls.The book will also be a helpful guide during review of clinical cases since the reader can look up specific imaging artifacts or pitfalls in the index. Featuring over 375 high quality images, numerous case examples, and concise, clinically oriented discussion of the physics behind the images, Practical MR Physics is an ideal resource for anyone who works in the field of MR imaging.

Naked to the Bone: Medical Imaging in the Twentieth Century (Sloan Technology Series) Review

Naked to the Bone: Medical Imaging in the Twentieth Century (Sloan Technology Series)
Average Reviews:

(More customer reviews)
I love reading science books geared toward non-scientists such as I. Bettyann Holtzmann Kelves Naked to the Bone: Medical Imaging in the Twentieth Century exactly fit the bill. Profusely illustrated and gracefully written, this fine work of non-fiction tells the story of x-rays, CT scan, MRI, sonograms, and PET scans. Kelves writes for the non-scientist, and does an excellent job of explaining how these various machines work, how they were perceived at the time, the economics of their development and marketing (Kelves never forgets that, for better or worse, medicine and inventing have always been businesses), and their changes in perception and use over time. Perhaps most interesting, and unexpected, are her two chapters addressing how medical imaging -- the ability to see "bones and all" -- was itself imaged in and influenced the visual, literary, and fine arts. Of particular interest to me, as a lawyer, is her accounts of how x-rays and other imaging devices were first used, and then later relied upon (or rejected) in courts of law. The depth and breadth of her research are truly impressive, as is her fine prose.

Improvisational Therapy: A Practical Guide for Creative Clinical Strategies Review

Improvisational Therapy: A Practical Guide for Creative Clinical Strategies
Average Reviews:

(More customer reviews)

Dr. Keeney presents a wealth of information in a small volume. Little time is wasted on theory and the question "Why?". Most of the book is devoted to explicit descriptions of techniques that can be powerful techniques of change.

In the first third of the book, Dr. Keeney describes a number of techniques from the MRI, forerunners of many of today's "power therapies".

In the second third, Keeney describes a method that makes use of an art gallery as a metaphor for conducting psychotherapy. His use of the idea of "frames' is especially useful given that Keeney maps out many of the possible ways a client's "frames of reference" can be influenced for change.

In the final third, Dr. Keeney presents a self-development exercise useful to the begining and the experienced therapist. Through the use of open-ended questions, Keeney guides the reader through a process that can enhance self-awareness and point to areas of professional growth.

In conclusion, I would recommend this slim volume to any therapist who is thirsting for practical and useful techniques.

In this unusual volume, Bradford Keeney depicts psychotherapy as a performing art. Emphasizing the advantages of improvising one's own therapeutic style, he presents a host of tried-and-true strategic interventions, a short course on brief intervention design, a way of "scoring' conversations with clients much like one would score music, a collection of therapeutic moves, and chapters on creating one's own clinical design. As such, IMPROVISATIONAL THERAPY is a book that will be valued by all who do clinical work.

Principles of Magnetic Resonance Imaging: A Signal Processing Perspective Review

Principles of Magnetic Resonance Imaging: A Signal Processing Perspective
Average Reviews:

(More customer reviews)
Magnetic resonance has recently recieved many riches in the form of excellent, definitive texts that have bundled together the advances of the last 20 or so years. Drs. Liang and Lauterbur have added to this trove by writing a text that goes beyond the standard descriptions of magnetic resonance image formation and including many advanced techniques available today, some of which they originated. The ideal audience for this text includes scientists, engineers, and physicians actively developing MRI applications from the physics on up. Though containing many recent developments it contains a core of medical imaging information that will not be outdated. The mathematical depth is sufficient to serve as a reference of basic and sophisticated methods but with enough pedagogical information to tutor the interested student. Liang and Lauterbur should be on the shelf of any serious professional or insightful student.

In 1971 Dr. Paul C. Lauterbur pioneered spatial information encoding principles that made image formation possible by using magnetic resonance signals. Now Lauterbur, "father of the MRI", and Dr. Zhi-Pei Liang have co-authored the first engineering textbook on magnetic resonance imaging. This long-awaited, definitive text will help undergraduate and graduate students of biomedical engineering, biomedical imaging scientists, radiologists, and electrical engineers gain an in-depth understanding of MRI principles.
The authors use a signal processing approach to describe the fundamentals of magnetic resonance imaging. You will find a clear and rigorous discussion of these carefully selected essential topics:
Mathematical fundamentals
Signal generation and detection principles
Signal characteristics
Signal localization principles
Image reconstruction techniques
Image contrast mechanisms
Image resolution, noise, and artifacts
Fast-scan imaging
Constrained reconstruction
Complete with a comprehensive set of examples and homework problems, Principles of Magnetic Resonance Imaging is the must-read book to improve your knowledge of this revolutionary technique.

Principles of Nuclear Magnetic Resonance Microscopy Review

Principles of Nuclear Magnetic Resonance Microscopy
Average Reviews:

(More customer reviews)
Dr. Callaghan's work over the past 15 years has been instrumental in developing microscopic applications of NMR imaging. In this text, he expands on the seminal papers that he has published in the field and brings them together into a coherent whole. The veiwpoint of the book is that of a physicist with a powerful tool looking at physical and biological problems. Of the many texts on MR imaging I believe Dr Callaghan's description of MR physics to be most clear and complete. This book is recommened for physicists and engineers interested in NMR microscopy of course. However I would go on and recommend it for any serious student of MRI wanting a single volume that has a clear description of the fundamental phenomena at work in forming their images.

Although nuclear magnetic resonance is perhaps best known for its spectacular utility in medical tomography, its potential applicability to fields such as biology, materials science, and chemical physics is being increasingly recognized as laboratory NMR spectrometers are adapted to enable small scale imaging.This excellent introduction to the subject explores principles and common themes underlying two key variants of NMR microscopy, and provides many examples of their use. Methods discussed are not only important to fundamental biological and physical research, but have applications to a wide variety of industries, including those concerned with petrochemicals, polymers, biotechnology, food processing, and natural product processing.The wide range of scientists interested in NMR microscopy will want to own a copy of this book.

Electromagnetic Analysis and Design in Magnetic Resonance Imaging (Biomedical Engineering) Review

Electromagnetic Analysis and Design in Magnetic Resonance Imaging (Biomedical Engineering)
Average Reviews:

(More customer reviews)
In spite of the importance of a coil in MRI, such as gradient and RF coil, there are few books on it. So many books on MRI. But they have been focused only on the imaging method or the basic principles of MRI.
This is the only guide book on RF and gradient coil, as I have found, and deals with current topics on the analysis and design on the hardware of MRI. Also, the references on each topics are well arranged and very useful.
