Pictorial Information Systems in Medicine

This volume contains the proceedings of the NATO Advanced Study Institute on "Pictorial Information Systems in Medicine" held August 27-September 7, 1984 in Hotel Maritim, Braunlage/Harz, Federal Republic of Germany. The program committee of the institute consisted of KH Hohne (Director), G. T Herman, G. S. Lodwick, and D. Meyer-Ebrecht. The organization was in the hands of Klaus Assmann and Fritz Bocker In the last decade medical imaging has undergone a rapid development New imaging modalities such as Computer Tomography (CT), Digital Angiography (DSA) and Magnetic Resonance Imaging (MRI) were developed using the capabilities of modern computers. In a modern hospital these technologies produce already more then 25% of image data in digital form. This format lends itself to the design of computer assisted Information systems Integrating data acquisition, presentation, communi cation and archiving for all modalities and users within a department or even a hospital. Advantages such as rapid access to any archived Image, synoptic presentation, computer assisted image analysis to name only a few, are expected. The design of such pictorial information systems, however, often called PACS (Picture Archiving and Communication Systems) In the medical community is a non-trivial task involving know-how from many disciplines such as - Medicine (especially Radiology), - Data Base Technology, - Computer Graphics, - Man Machine Interaction, - Hardware Technology and others. Most of these disCiplines are represented by disjunct scientific communities.

Natural Language Communication with Pictorial Information Systems

This book contains the reports of selected projects involving natural language commu nication with pictorial information systems. More than just a record of research results, however, it presents concrete applications to the solution of a wide variety of problems. The authors are all prominent figures in the field whose authoritative contributions help ensure its continued expansion in both size and significance. Y. C. Lee and K S. Fu (Purdue University, USA) survey picture query languages which form an interface between the pictorial database system and the user and support infor mation retrieval, data entry and manipulation, data analysis and output generation. They include explicit picture query languages that augment alphanumeric data query langua ges as well as languages and command sets which are implicitly embedded in a pictorial information system but perform similar functions. It is worth mentioning that some forms of query languages can be transformed from a given set of natural language senten ces by using ATN (Augmented Transition Networks), which consequently allows for na turallanguage communication with information system.

Advances in Visual Information Systems

Presently, in our world, visual information dominates. The turn of the millenium marks the age of visual information systems. Enabled by picture sensors of all kinds turning digital, visual information will not only enhance the value of existing information, it will also open up a new horizon of previously untapped information sources. There is a huge demand for visual information access from the consumer. As well, the handling of visual information is boosted by the rapid increase of hardware and Internet capabilities. Advanced technology for visual information systems is more urgently needed than ever before: not only new computational methods to retrieve, index, compress and uncover pictorial information, but also new metaphors to organize user interfaces. Also, new ideas and algorithms are needed which allow access to very large databases of digital pictures and videos. Finally we should not forget new systems with visual interfaces integrating the above components into new types of image, video or multimedia databases and hyperdocuments. All of these technologies will enable the construction of systems that are radically different from conventional information systems. Many novel issues will need to be addressed: query formulation for pictorial information, consistency management thereof, indexing and assessing the quality of these systems. Historically, the expression Visual Information Systems can be understood either as a system for image information or as visual system for any kind information.

Management and Office Information Systems

Management and Office Information Systems

Decision making is a very complex phenomenon. Modern decision makers must deal with very complex problems which are constantly changing and often ill structured, making modeling and analysis difficult. In order to provide support for the decision makers, computer-based information systems are designed to collect, store, process, and transport information. Recent advances in computer technol ogy, data communications, database systems, office automation, and knowledge engineering have made possible the design of very sophisticated information sys tems. However, rapid technological advances also create many problems, not the least of which is the lack of integration among the various disciplines in infor mation system design. Without such integration, a costly computer-based infor mation system is at best partially useful and at worst totally useless. The aim of this book, therefore, is to examine the various issues involved in designing man agement information systems, decision support systems, and office information systems for increasing productivity and providing decision support. This book is the outcome of the Workshop on Management and Office Infor mation Systems, which was organized by the Knowledge Systems Institute and held at Chicago, Illinois, from June 28 to 30, 1982. Twenty-seven papers from the working papers presented at that workshop were selected for inclusion in the present volume, which is organized into five parts: (I) organization structures and management, (II) decision support systems, (III) database systems, (IV) office information systems, and (V) systems and applications.

Volume 9 of this series on information systems science presents four timely topics of current interest in this growing field. In each chapter an attempt is made to familiarize the reader with some basic background information on the advances discussed, so that this volume may be used independently or in conjunction with the previous volumes. The emphasis in this volume is on data structures for scene analysis, database management technology, inductive inference in processing pattern-based information, and logic design of MOS networks. Scene analysis has become a very important aspect in information system design. The process of scene analysis involves sensing, segmentation, recognition, and interpretation. Innovative development of algorithms for these tasks requires the utilization of structural relationship prevalent within the sensed data. In Chapter 1, Thomason and Gonzalez discuss the formula tion of data representation techniques and the properties of data structures and databases in scene analysis. In view of the growing importance of database management, Chapter 2 is devoted to an overview of database management technology. In this chapter Kobayashi covers a variety of current topics. The topics discussed include system design methodology, data structure theory, semantic con siderations, calculus-based database operations, database management functions, and the issues of integrity, security, concurrency, and recoverabil ity. This chapter also discusses the end-user languages and several existing database management systems.
