This book is a welcome introduction for readers who are comfortable with basic differential equations and vector calculus. As an applied mathematician interested in learning the fundamentals of MRI, I had grown quite frustrated with the simplified literature on one hand ("MRI for technologists", "MRI for medical people", "MRI for dummies"...) and the professional literature on the other, which is directed at people already immersed in the study of MR technology. In contrast, this book is an excellent introduction to the subject for applied mathematicians (though this may not have been the intended audience), as it makes no assumptions regarding reader's science background and thus explains thoroughly all relevant E+M, physics and signal processing. But most importantly, it does so without cutting mathematical corners. This results in a far more lucid and logical exposition than books which try to protect the reader for his/her own good.
