Radiochemical methodology constitutes the most important base for the successful functioning of a PET group in the routine production and development of radiopharmaceuticals. Of the several hundred products which have been labelled with positron emitters during the past two decades about 35 are presently considered to be of major interest. The time for a state-of-the-art review is right, since this field has advanced over the past fifteen years to reach a level where guidelines can now be suggested. Chapters of this book deal with each of the main methodological aspects of the chemistry needed to develop an effective radiopharmaceutical, namely radionuclide production, automation and metabolite analysis. A further chapter on QA/QC is written by a broadly-based expert group and is meant to provide a guideline and a base for future monographs and regulations on major PET radiopharmaceuticals of today. This book will help the increasing numbers of scientists who are now entering the field of PET to appreciate the methodological aspects that are normally addressed by chemists in relation to PET radiopharmaceuticals; it provides many useful practical guidelines and will promote early success in their own endeavours, since these will often necessarily begin by establishing chemical methodology of the kind discussed here.
Parameters such as membrane transport, metabolism and protein incorporation govern the fate of amino acids in living tissue. Is it possible to use positron tomography to measure some of them, and what is their meaning in normal and pathological situations? These questions have been addressed for a long time and no satisfactory answer has yet been given. This book, which derives from an EEC workshop organized in the frame of the Concerted Action on "PET Investigation of Cellular Regeneration and Degeneration", held in Lyon in February 1992, gives the present state of knowledge in this field based on the most recent studies. Contributions from 24 leading European and American scientists are presented and discussed.

Since the introduction of myocardial perfusion imaging and radionuclide angiography in the mid-seventies, cardiovascular nuclear medicine has undergone an explosive growth. The use of nuclear cardiology techniques has become one of the cornerstones of the noninvasive assessment of coronary artery disease. In the past 15 years major steps have been made from visual analysis to quantitative analysis, from planar imaging to tomographic imaging, from detection of disease to prognosis, and from separate evaluations of perfusion, metabolism, and function to an integrated assessment of myocardial viability. In recent years many more advances have been made in cardiovascular nuclear imaging, such as the development of new imaging agents, reevaluation of existing procedures, and new clinical applications. This book describes the most recent developments in nuclear cardiology and also addresses new contrast agents in MRI. What's New in Cardiac Imaging will assist the clinical cardiologist, the cardiology fellow, the nuclear medicine physician, and the radiologist in understanding the most recent achievements in clinical cardiovascular nuclear imaging.

The 1991 International Conference on Information Processing in Medical Imaging (IPMI '91) is the twelfth in the series and was held in Wye College, part of the University of London. The purpose of IPMI is to provide a forum for the detailed examination of methodological issues in computing which are at the heart of advances in medical image formation, manipulation and interpretation. This volume presents the proceedings of IPMI '91. Full-length scientific papers describing the latest techniques and results are organized into the following nine sections: - Image formation and reconstruction - Incorporation of priors in tomographic reconstruction - Multi-modal registration - Segmentation: specific applications - Segmentation: multi-scale, surfaces and topology - Anatomical models and variability - Factor analysis - Rule based systems and learning - Image quality, display and interaction. The volume also includes a set of color plates and a subject index. The book provides an up-to-date account of current work in the expanding and fast-moving area of image processing and medical imaging, and gives an overview of work at all the key centers researching in this area. It will prove an invaluable asset to all researchers working in the area and to the libraries of organizations involved in imaging research.
The second E. C. Workshop on Ultrasonic Tissue Characterization was organized for the assessment of research goals and plans as the basis to a grant proposal for a "Concerted Action" which will be forwarded to the European Commission. It should, therefore, not only be considered as a work in progress exhibition which succeeded the former activities within the E. C. (Inventory on Tissue Characterization in Europe and first Workshop). The Steering Group invited a 1 imited group of Institutes to send its group leader and a research fel low in the entitled field, who should expose the overall research program, as wei 1 as the more specific work on tissue characterization by RF signal analysis and spectroscopy. The ultimate goal of the Workshop has been the formulation of schemes of interaction among the Institutes and individuals and the definition of cooperative research programs. The remainder of the groups and some of the groups present are working in the field of analysis and processing of cl inical A- and B-mode echograms (i. e. video signals). Because this work is more closely related to the cl inical diagnostics it was decided that for that reason no preparatory workshop was needed. In the final proposal for the Concerted Action this work wi 1 1 get ample attention. Although not many clinicians were present, their positive interest in the sophisticated analysis techniques and their contribution to the dis cussions again have been a most valuable and stimulating experience.

Recent developments in the ultra-short laser technology and physics, especially at the attosecond time scale, open up new research frontiers for attoscience. This book examines the theoretical model for attophysics. The interaction of the attosecond laser pulses with slices of matter-attosecond tomography enables the description of the motion of electrons in atoms, molecules and 1D medium-graphene. The standard theory of the laser pulse-matter interaction is based on the parabolic Schrodinger equation, which leads to unphysical, infinite velocity of the thermal energy propagation. In this book, the Schrodinger equation is generalised to hyperbolic partial differential equation with finite velocity.
The principle of tomography is to explore the structure and composition of objects non-destructively along spatial and temporal dimensions, using penetrating radiation, such as X- and gamma-rays, or waves, such as electromagnetic and acoustic waves. Based on computer-assisted image reconstruction, tomography provides maps of parameters that characterize the emission of the employed radiation or waves, or their interaction with the examined objects, for one or several cross-sections. Thus, it gives access to the inner structure of inert objects and living organisms in their full complexity. In this book, multidisciplinary specialists explain the foundations and principles of tomographic imaging and describe a broad range of applications. The content is organized in five parts, which are dedicated to image reconstruction, microtomography, industrial tomography, morphological medical tomography and functional medical tomography.
Imagining the Elephant is a biography of Allan MacLeod Cormack, a physicist who was awarded the Nobel Prize for Medicine in 1979 for his pioneering contributions to the development of the computer-assisted tomography (CAT) scanner, an honor he shared with Godfrey Hounsfield. A modest genius who was also a dedicated family man, the book is a celebration of Cormack's life and work. It begins with his ancestral roots in the far north of Scotland, and then chronicles his birth and early years in South Africa, his education at the University of Cape Town (UCT) and Cambridge University, and his subsequent academic appointments at UCT and Tufts University in Boston, USA. It details his discovery of the problem at Cape Town in 1956, traces his scientific footsteps all the way to Stockholm in December 1979, and then extends the odyssey to his pursuits beyond the Nobel Prize. |
