Computational methodologies of signal processing and imaging analysis, namely considering 2D and 3D images, are commonly used in different applications of the human society. For example, Computational Vision systems are progressively used for surveillance tasks, traf?c analysis, recognition process, inspection p- poses, human-machine interfaces, 3D vision and deformation analysis. One of the main characteristics of the Computational Vision domain is its int- multidisciplinary. In fact, in this domain, methodologies of several more fundam- tal sciences, such as Informatics, Mathematics, Statistics, Psychology, Mechanics and Physics are usually used. Besides this inter-multidisciplinary characteristic, one of the main reasons that contributes for the continually effort done in this domain of the human knowledge is the number of applications in the medical area. For instance, it is possible to consider the use of statistical or physical procedures on medical images in order to model the represented structures. This modeling can have different goals, for example: shape reconstruction, segmentation, registration, behavior interpretation and simulation, motion and deformation analysis, virtual reality, computer-assisted therapy or tissue characterization. The main objective of the ECCOMAS Thematic Conferences on Computational Vision and Medical Image Processing (VIPimage) is to promote a comprehensive forum for discussion on the recent advances in the related ?elds trying to id- tify widespread areas of potential collaboration between researchers of different sciences.

This work has true international scope, being a unique European/American joint venture that focuses on the state of the art in both diagnostic and therapeutic radionuclide methodology. Pertinent clinical applications are emphasized rather than attempting to cover everything included in the several large comprehensive texts available in our field. This "practical" approach should make it an essential guide to nuclear medicine physicians, technologists, students and interested clinicians alike.

Radiation safety and risk management, a critical issue in the nuclear age, is an ongoing concern in the field of radiation health risk sciences. It is the particular mission and task of the Nagasaki University Global COE program to explore human health risks from radiation on a global scale and to come up with measures for overcoming its negative legacies. Ionizing radiation is a well-documented human cancer risk factor, and long-term health consequences in individuals exposed at a young age to such events as the Hiroshima and Nagasaki atomic bombing are now being followed up. Unique and comprehensive, this book introduces updated radiation health-related issues, including the proper collection and analysis of biological samples, cancer research, psychological effects, fair disclosure, and the effects of low-dose exposure as they apply to future public health policy. Also addressed is the need for emergency radiation medicine in case of accidents.

Although in the last few years more experience in the field of epilepsy surgery with amygdalo-hippocampectomies was gained in several hos- pitals, a detailed microanatomical and microsurgical description meet- ing the requirements of the modern neurosurgeon has not been achieved so far. Recently the allocortex - the so-called "limbic system" - has doubtlessly received more attention, as can be gathered from the recently published monography by Duvernoy, which however only considers anatomical points of view. Lately not only epilepsies but also tumorsurgical operations on the border between temporal lobe and basal ganglia can be - thanks to modern MR-examinations - carried out more exactly. Here the tumor-conditioned deformations of the temporo-medial area and its connections with the adjacent basal gang- lia as well as their blood supply are of great importance. Using conven- tional techniques the postoperative morbidity was especially high until recently. The author has at the suggestion of his teacher G. M. Ya argil approached the problem first of all morphologically by developing his own techniques of brain dissection. After some developmental and topographic-anatomical descriptions he has described the vessel-supply by using injection-preparations. Particular aspects of A. chorioidea ant. with her lateral, medial and Tractus opticus penetrating perforat- ing arteries to the basal ganglia and Capsula into have never been described in such a convincing manner before. It is of great importance in the operative removal of the amygdalo- hippocampal area to realize that it is not sufficient to preserve the A.

Medical Management of Heart Failure brings together the current knowledge on the medical management of heart failure into one cohesive volume. It includes copious illustrations and photographic material that will explain the techniques and medical management of patients with heart failure in an effective modern format.

Plain radiography is still alive. In many institutions, including ours, conventional radiography has been replaced by digital systems including imaging-plate-based computed radiography and fat-panel detector-based digital radiography. Even for the education of radiation technologists, conventional flm-screen radiography has been de-- phasized, and their education is concentrated on digital systems. Spatial resolution of a conventional system is still far better than the current digital systems, although the dynamic range is wider in the latter system. Industrial flm radiography with small grain size and direct exposure has an even higher resolution, and such hi- resolution systems are something we lost in the transition from the conventional system to the current PACS-friendly system. I am pleased to know that Giuseppe Guglielmi and Wilfred Peh have published this textbook of high-resolution hand radiographs that cannot be obtained with any other techniques. Radiography has always been the most important modality in the evaluation of the hand, and, moreover, high-resolution industrial flms are extremely efective in the evaluation of the hand, particularly for assessing subtle erosions. Hands are not just one of the peripheries of the human body. Tey refect conditions of the whole human body. Not only the metabolic status, but also many congenital disorders are manifested in the hand. Radiographic fndings of the hand are ofen specifc, and contribute to the diagnoses a great deal. Tere have been several publications concerning the radiology of the hand, and they have been well accepted.

The sober explanation for this book is a call by the Springer-Verlag, London, to edit a publication on 'The functional relevance of the collateral circulation' of the heart. Alternatively, it could be 'sold' as the result of my intention to reduce entropy of 18 years of scientific work on the topic of the coronary circulation, which was itself meant to diminish the amount of 'useless' energy. Such a process of reducing disarray in a system with the aim of grasping it better is related to simplification, which carries the risk of introducing error. This can be exemplified by the historic view of angina pectoris, which used to be simplified as being always fatal, thus obscuring for nearly two centuries the view of a 'self-healing' mechanism such as the collateral circulation of the heart. It would be na?]ve, to assume the present work to be free of erroneous oversimplification, because the very nature of scientific work is related to generating (simple) hypotheses with their subsequent falsification. In that context and bluntly, my primary interest in the field of the collateral circulation was not initiated with a vision of eradicating the consequences of coronary artery disease (CAD) by promoting the growth of natural bypasses. The time for such sizeable ideas had passed in the 1970s with the start of the work by Wolfgang Schaper."

Endovascular Neurosurgery represents a unique collaboration between contributors from a number of specialties, all of whom are concerned with the management of cerebrovascular disease. This provides a balanced account of the efficacy of interventional endovascular techniques in this group of conditions. As a result, Endovascular Neurosurgery will prove an invaluable account of a relatively new specialty and will be essential reading for neurosurgeons, neurologists, neuroradiologists, neurophysiologists and neuroanaesthetists.

This is the first book to cover minimal-invasive treatment of osteoporotic, tumorous and traumatic vertebral fractures in the English language. In addition to detailed descriptions of the techniques, including tips and tricks from experts, the book contains a chapter about the medical treatment of osteoporosis, which is indispensable in the interdisciplinary approach to osteoporosis. This acclaimed innovative concept unites several treatment aspects. More conservative treatment methods are also presented in this work.

All chapters reflect new developments and clinical findings in the field of orthopaedics, surgery, traumatology and neurosurgery.

Imaging procedures have been used for many years and are becoming increasingly important in a number of medical disciplines. This is due to recent technological advances, primarily computerization. The meth ods employed in CNS diagnostics are collectively referred to as "neu roimaging" and include procedures for investigating both cerebral morphology and cerebral function, such as computed tomography (CT), magnetic resonance imaging (MRI), positron emission tomogra phy (PET), and single-photon emission computed tomography (SPECT). Topographic mapping of electroencephalograms (EEG) and evoked potentials represents one of the functional procedures and per mits topographic imaging of EEG, evoked potentials, and magnetic fields. The latter application includes not only magnetic fields evoked by stimuli relating to different sensory modalities, but also endogenous and motor fields resulting from spontaneous brain magnetic activity, as recorded by magnetoencephalograms (MEG), the magnetic comple ment of the EEG. The advantage of recording electric and magnetic fields over other neuroimaging procedures is that these techniques are completely noninvasive and have extremely short analysis times (in the millisecond range). The aim of this book is to clarify the current state of this emerging technology, to assess its potential for substantive contributions to brain research, to delineate areas for further research and, over all, to envis age clinical applications in disciplines such as psychiatry, neurology, and neuropsychology."

Malignant growth of cells is often characterized by disorganization of tissue structure, abnormal blood vessel development, and insuffi cient vascular supply. As a consequence, the cancer cells grow in a three-dimensional pattern in atypical microenvironments which include physical, chemical, and nutritional stresses. Necrosis often develops some distance away from the blood vessels. In association with an inherent instability in malignant cell populations, and also because of the changing micromilieu, significant cellular heteroge neity emerges with regard to various phenotypic characteristics. Both biological behavior and responses to therapeutic agents can be affected. A variety of in vitro and in vivo experimental models exist for research on properties of cancer cells during growth. The multicell spheroid model was developed as a system of intermediate complexity in which three dimensional growth of cells enhances cell-cell interactions and creates micro environments that simulate the conditions in intervascular microregions of tumors or microme tastatic foci. Spheroids may change their cellular characteristics with changing environments during growth. These can be studied under controlled conditions in vitro. Interest in details of experimental methods for this model system stimulated the organization of the First International Conference in Rochester, NY in 1980, the Proceedings of which were summarized in Cancer Research in 1981. Since then there has been a rapid increase in the use of this model system, and increased research on the significance of cell-cell and cell-microenvironment interactions in biology in general."

The eighth annual multidisciplinary symposium on clinical oncol ogy organised by the Royal College of Radiologists discussed the subject of investigational techniques in oncology. It was held in London in February 1986. This volume collects together the edited texts of the papers which were presented at the meeting, together with the George Edelstyn memorial lecture given by Professor J. Einhorn. Clinicians rely very heavily on pathologists and radiologists to help with the diagnosis and staging of patients who present with malignant tumours. The conventional techniques to which we have become accustomed are fast being supplemented by exciting new approaches. These have moved very rapidly from being purely experimental techniques to being a part of routine clinical practice. Some of these new approaches have been highlighted in this symposium. Recent advances in molecular biology have produced various specific techniques for looking at phenotypic changes in cells as detected by immunohistochemical probes. Visualisation of genes and their transcripts in human biopsies has become a real possibility using a wide and increasing range of molecular probes. Some of the advantages of these techniques and their potential for the future are presented here."

The purpose of this series of volumes is to present a comprehensive view of the complications that result from the use of acceptable diagnostic and thera peutic procedures. Individual volumes will deal with iatrogenic complications involving (1) the alimentary system, (2) the urinary system, (3) the respiratory and cardiac systems, (4) the skeletal system and (5) the pediatric patient. The term iatrogenic, derived from two Greek words, means physician-in duced. Originally, it applied only to psychiatric disorders generated in the patient by autosuggestion, based on misinterpretation of the doctor's attitude and comments. As clinically used, it now pertains to the inadvertent side effects and complications created in the course of diagnosis and treatment. The classic categories of disease have included: (1) congenital and developmen tal, (2) traumatic, (3) infectious and inflammatory, (4) metabolic, (5) neoplastic, and (6) degenerative. To these must be added, however, iatrogenic disorders a major, although generally unacknowledged, source of illness. While great advances in medical care in both diagnosis and therapy have been accomplished in the past few decades, many are at times associated with certain side-effects and risks which may result in distress equal to or greater than the basic condi tion. Iatrogenic complications, which may be referred to as "diseases of medical progress," have become a new dimension in the causation of human disease."

In Videofluorscopic Studies of Speech in Patients with Cleft Palate, Drs. M.L. Skolnick and E.R. Cohn present multiview videofluoroscopy as a technique for the radiological evaluation of speech defects in patients with cleft palate. Dr. Skolnick's invaluable contributions as both the originator and leading authority on the subject are discussed in a concise, clinical fashion. Topics examined include the anatomy and imaging of the velopharyngeal portal; the equipment and techniques of multiview videofluoroscopy; the interpretation of results and various patterns of velopharyngeal closure; Passavant's Ridge and patterns of velopharyngeal closure; normal and abnormal speech production; and the evaluation of test results. This book is the only source which concisely and completely describes the technique and its interpretations for those who need a description of the clinical procedure.

The diagnosis of osteoporosis and the determination of fracture risk has always been a challenge for radiologists, epidemiologists, and clinicians as well as oth er researchers and health care professionals working in the field. It is bone min eral density that is closely related to bone fragility, and the advent of techniques to quantitatively assess bone density has been welcomed. It has reduced the sub jectivity inherent to conventional radiologic assessment of osteoporosis. The on going technical process has made various techJ)iques to assess bone density wide ly available. However, these measurement techniques have also incurred some crit icism because bone densitometry has sometimes been applied without specific indications and without appropriate clinical ramifications. The purpose of this text is to provide a perspective on the current status of bone densitometry and ist relevance to osteoporosis diagnosis and management. Therefore, this book will give the reader an introduction to the nature of osteo porosis, its pathophysiology and epidemiology, and the clinical consequences of performing bone densitometry. Aside from standard bone densitometry, newer technologies such as quantitative ultrasound techniques, magnetic resonance imaging and bone structure analysis are discussed in the context of diagnosing osteoporosis."

Advanced Renal Cell Carcinoma (RCC) cannot be cured by surgery alone. Its resillience to irradiation and chemotherapy demands a new approach to the management of this disease. This book provides an overview of the scientific and clinical developments of RCC, and clarifies the fields ofimmunotherapy and immunobiology. The book contains a compilation of approaches that will enhance the effectiveness of the management of advancedRCC, even in the absence of definitive pre-clinical data. These require additional study and will stimulate the reassessment of preliminary results.Furthermore, preliminary results of already implemented clinical trials withbiological modifiers are presented. Of special interest are the current achievements in the field of immunotherapy using topically and subcutaneously low dosage combinations of cytokines. This concise volume will benefit those seeking a thorough review of the research and the clinical aspects of RCC simultaneously.

There has long been disagreement about various aspects of the structure and function of the "gatekeeper" (Greek pyloros, from pyle = gate and ouros = guard). In recent years the problem has often been mentioned in anatomy, physiology, gastroenterology, radiology and even in nuclear medicine. For instance, while referring to manometric and gastric emptying studies, Schu- urkes and van Nuenten (1984 ) pointed out that there was considerable contro- versy as to whether a true pyloric sphincter existed in most species, and espe- cially in man. According to Reeve (1981) many functional aspects of sphincters are poorly understood; the exact mechanism of control of the transfer of chyme from stomach to duodenum through the pylorus is still not clear. Malagelada (1983) states that controversy surrounds the motor activity and function of the antro- duodenal junction; there is disagreement as to whether the pylorus functions as or as an integral part of the distal antrum. Ehrlein et al. (1984) a separate unit reiterate that pyloric motility is poorly understood, and according to Funch- Jensen (1987) there are many unsolved questions. Malagelada (1990) states that the stomach performs multiple functions with a deceivingly simple anat- omy; this is regarded as the key to the investigator's frustration when trying to uncover its secrets. One source of the many controversies surrounding the pylorus may be species differences, according to Schulze-Delrieu et al. (1984).

The contributions in this book were originally presented at the workshop "Research and Clinical Application of Isolated Liver Perfusion for Hepatic Tumors" held on 28 February to 1 March 1997 in Hanover, Germany. The workshop was planned to bring together groups working with isolated liver perfusion techniques worldwide. Experts from various countries were invited to pre sent and discuss their experimental data and clinical results. USA par Groups from Japan, The Netherlands, Sweden and the ticipated. At the beginning, oncologists, surgeons and patholo gists presented possible indications and the oncological back ground for therapeutic isolated liver perfusion from their points of view. Based on data from previous studies about loco regional chemotherapy and based on the pathology of metastasis, it could be concluded that there is a place for isolated liver perfusion in the therapy of liver cancer. Second, different surgical techniques of isolated liver perfusion were presented. These techniques var ied from a percutaneous approach with extracorporeal chemofil tration to extended open abdominal surgery. Perfusion of the liv er without a considerable amount of drug reaching the systemic circulation proved to be possible. The complex procedure with complicated extracorporeal perfusion technique represented a disadvantage of the methods presented. Further studies should simplify the technical and surgical aspects. Intraoperative and postoperative management of . patients undergoing isolated liver perfusion were also discussed. Coagulopathy was one important aspect which can occur during isolated liver perfusion. The per centage of leakage determined systemic side effects."
