ABSTRACT
In this paper, the design and development of Computer Assisted Information Resources Navigation (CAIRN) is discussed. CAIRN system is a medical information retrieval system that allows physicians and students to store full text medical information from any resource, organize and retrieve it. The most important feature of CAIRN is its capability to assist the user, physician, student etc. in selecting documents against a submitted query in Natural Language. The retrieved documents are presented in decreasing order according to their similarity to the submitted query. The nearest neighbour method is used. An alternative similarity measure based on a new calculation of the length of documents is proposed and some experimentation with it is discussed.

Quality control tests for CT scanners are very important for correct machine performance, and for the radiation protection of patients and medical personnel. As proliferation of CT scanners continues, the need for distributable software tools to perform quality control tests becomes evident. A multimedia tool and guide will help medical physicists and technologists to perform these tests easily and correctly. The guide can be easily accessible in CD-ROM, or networked on the Internet. The user, medical physicist or technologist, can find in the present guide the pertinent theoretical information and the procedures necessary to perform the quality control tests, with the help of texts, CT images and photographs, narration and video. The results of the tests are automatically compared with machine specifications and acceptable values set by international bodies, and are stored in a table.

In this paper the authors present the basic results of the study for the "TELE.INFO.MED.LAB" project. This study is based on the local experience of the Metaxas Cancer Institute case and on international references. The possibilities rendered by current developments in telemedicine and particularly in telepathology accelerate and facilitate the communication of crucial medical data and creation of "second level" medical services overcoming the geographical particularities of the country. The availability of data transmission (signals, images, texts, etc.) enables the creation of a "uniform market" for various services. This system must take into account the financial realities, geographical aspects transportation problems and technological developments. Organization of this system, the choices of technical standards and the realization of a complete pilot project are described. For this system we also describe the functional and technical aspects, as well as software and hardware components for the different types of units.

In a medical information system there is a serious need for assessing patient information in various ways. There is also a need for summarizing information in simple statistical tabular form. In this part we present and evaluate different techniques for query formulation, such as: QBE (Query-by-Example), SQL (Structured Query Language), GCL (Graphical Query Language). We also present a query processor for use in a pathology information system. This software system incorporates: a) A semi graphical tree structure interface (SGTSI) for query formulation, and b) Summary tables handling.

This paper deals with the description of a telecommunication project which is initiated by Metaxas Pathology Laboratory. In the first section we discuss a comprehensive computer supported information system which was installed in the laboratory. Special emphasis is given at the design of the communication subsystem. Then, the configuration of the diagnostic equipment is described. The last section of the paper focuses on the discussion of the experimental use of an integrated "low cost" system for interconnection among the Metaxas Pathology laboratory, the Pathology Department of the University of Crete, and the Technological Educational Institute (TEI) of Athens.

Architecture of a new medical documentation system (MDS) is proposed. First, we studied the traditional MDS in terms of organizational structure, main functions, means (resources) and personnel. Special emphasis is given to the information retrieval (IR) system which is the kernel of a MDS. Then, some achievements of information technology is summarized, and concept of a mixed IR system which is the kernel of the new system is presented. New architecture is then presented. Units which compose the entire system are: host documentation centre, local documentation centres, and documentation units. Eventually, objective and features of every part are discussed.
