Mri Physics

Magnetic Resonance Imaging is a very important clinical imaging tool. It combines different fields of physics and engineering in a uniquely complex way. MRI is also surprisingly versatile, 'pulse sequences' can be designed to yield many different types of contrast. This versatility is unique to MRI. This short book gives both an in depth account of the methods used for the operation and construction of modern MRI systems and also the principles of sequence design and many examples of applications. An important additional feature of this book is the detailed discussion of the mathematical principles used in building optimal MRI systems and for sequence design. The mathematical discussion is very suitable for undergraduates attending medical physics courses. It is also more complete than usually found in alternative books for physical scientists or more clinically orientated works.

MRI Physics for Radiologsits: A Visual Approach, Third Edition delineates the principles of magnetic resonance imaging in a format that can be understood by readers who do not have a sophisticated physics or mathematics background. It is organized in three sections: sections one and two present the contrast and spatial characteristics of the image; section three deals with topics such as Half Fourier imaging, motion, aliasing, artifacts, and coils. The third edition has sections on new techniques now in common use, such as rectangular field of view and fast spin-echo (or echo-planar) sequences, a chapter on the effect of MR equipment parameters on image resolution, a chapter with a simplified mathematical discussion of the Fourier transform and an enhanced section on magnetic resonance angiography.

A succinct introduction to the physics and function of magnetic resonance imaging with an emphasis on practical information. This thoroughly revised second edition is clearly structured. The underlying physical principles of the MR experiment are described and the basic pulse sequences commonly used in clinical MRI. It progresses to more advanced techniques such as parallel imaging and cardiovascular MR imaging. An extensive glossary offers rapid access to MRI terminology and will help those seeking to understand this interesting fascinating subject.
