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.Suitable for undergraduates attending medical physics courses.Also available in print.Mode of access: World Wide Web.System requirements: Adobe Acrobat Reader.Richard Ansorge is a senior lecturer in the Department of Physics at Cambridge University. His current interests include hardware and software development for various medical imaging modalities, especially PET and MRI. This work is done in close collaboration with the Wolfson Brain Imaging Centre. One particular current project is the development of a novel combined PET-MR system for pre-clinical research. Other projects involve MR sequence development and post-processing algorithms for MR and PET.Title from PDF title page (viewed on November 2, 2016).
