内容简介
本书是一部英文版的物理学专著。关于核磁共振成像的书籍已经很多了,那为什么还要再写一本呢?我们认为现有的大多数书籍要么是针对临床读者,要么着重于如何使用核磁共振并解释所得到的图像,要么相当抽象,尽管它们可能包含了大量的技术细节,但它们并不是对该主题的良好介绍.我们认为我们的书在这两个特别之间占据了一席之地,并且对于有工程或物理科学背景的读者来说,这是对核磁共振的意义深远的介绍。

作者简介
Richard Ansorge，a retired senior lecturer at the Cavendish Laboratory Cambridge and a former fellow and tutor of Fitzwilliam College Cambridge. He has extensive experience of experimental high energy physics, including significant contributions to the CERN UA5 experiment on the proton-antiproton collider in the 1980s. More recently he has collaborated with research groups on the Cambridge Biomedical campus in several areas including improving 3D medical imaging methods including MRI and PET. He is author of more than 100 scientific publications in these fields. He is particularly interested in applying computers for processing data from complex instrumentation. This has applications which are equally relevant in both high energy physics and medical imaging. He wrote his first computer program in 1964 for EDSAC2 and has been coding ever since. Much more recently he has developed code for 3D medical image registration using GPUs which are probably 10（10） times more powerful than EDSAC. Martin Graves，a Consultant Clinical Scientist and lead of the Cambridge University Hospitals MR Physics group. He also holds an Affiliated Lecturer position with the University of Cambridge Clinical School. He is a Fellow of the Institute of Physics and Engineering in Medicine （IPEM）, a Fellow of the Higher Education Academy （HEA）, member of the Institute of Engineering and Technology （IET） and is an Honorary Member of the Royal College of Radiologists （RCR）, He has served on various national and international committees including the British Institute of Radiology （BIR）, the International Society of Magnetic Resonance in Medicine （ISMRM） and the European Society of Magnetic Resonance in Medicine and Biology （ESMRMB）. He is a member of the editorial board of European Radiology.
