IS & C system and file protection mechanism.

This paper reports a new extension of IS & C (Image Save And Carry) project. Because IS & C is an off-line system and requires full compatibility so as to enable medical data interchange with ease among hospitals and clinics, specifications that are indispensable for compatibility have been standardized by the IS & C committee. The IS & C system is supposed to be used in medicine, so the file protection mechanism for the security of the recorded files has been also developed. The characteristics of IS & C volume and file structure and the second national project being carried out in National Cancer Center Hospital are briefly explained as well.

IS & C implementation of an image workstation.

The Image Save & Carry (IS & C) 5-inch magneto-optical disk system was introduced to a PACS image workstation so as to exchange digital image data between two independent PACS modules. The results showed that it was possible to connect two different PACS modules by off-line data transmission. Also, the IS & C standard software proved to be of high speed read/write performance for several data files on an image workstation. However, when the IS & C is implemented to the high resolution real-time digital radiography system, an image compression standard will be required to expand its capacity.

Image management and communication--a legal perspective.

This paper outlines the legal issues that arise in the context of digital diagnostic image management and communication. At the heart of the study is the digital image which is manipulated, processed, communicated, stored compressed and archived, and which is difficult to ascertain from a legal point of view because of its intangible nature. At issue is, on the one hand, data protection and security and, on the other hand, legal problems as to the images' evidential force, procedural and legal admissibility and most important uncertainties about the liabilities of those involved in handling the digital image.

Computational viewpoint of the OpenLabs architecture.

The computational viewpoint of the OpenLabs architecture specification concentrates on the definition of the functional interfaces between the logical modules that make up the clinical laboratory as defined in the enterprise and information viewpoints. A method is presented which transforms the information models into a specification written in Abstract Syntax Notation One (ASN.1). It is then shown how the specification can be translated into an Interface Definition Language (IDL) of a 'middleware' product which can then be compiled for implementation on a distributed system.

Patient result validation services.

Patient result validation is a vital final stage of laboratory quality assurance and is usually the responsibility of senior laboratory staff. Computerised validation systems have recently been introduced to autovalidate data meeting certain pre-defined criteria, thereby allowing senior staff to focus on problematic cases. This article describes the patient results validation service module developed for an advanced instrument workstation in the OpenLabs project. Using knowledge-based techniques, the module provides a range of locally configurable advanced validation procedures (e.g., internal consistency checks, delta checks, and checks for selected specific errors) in addition to the standard reference range and pathological limits checks offered by many laboratory information systems.

The research in semantics behind the OpenLabs coding system.

The OpenLabs coding system is an established, comprehensive, dynamic, flexible, open, multilingual European system which is tailored to meet the electronic data interchange (EDI) needs of medical laboratory users. The OpenLabs coding system, having many specific, independent classes and considerable flexibility, serves two different objectives: (i) unambiguous coding of entities present in messages used for EDI in clinical pathology; and (ii) interfacing with other nomenclatures and coding schemes to map concepts between different systems.

MULTI: a shared memory approach to cooperative molecular modeling.

A general purpose molecular modeling system, MULTI, based on the UNIX shared memory and semaphore facilities for interprocess communication is described. In addition to the normal querying or monitoring of geometric data, MULTI also provides processes for manipulating conformations, and for displaying peptide or nucleic acid ribbons, Connolly surfaces, close nonbonded contacts, crystal-symmetry related images, least-squares superpositions, and so forth. This paper outlines the basic techniques used in MULTI to ensure cooperation among these specialized processes, and then describes how they can work together to provide a flexible modeling environment.

Chemical collaboratories using World-Wide Web servers and EyeChem-based viewers.

We present a "proof-of-concept" model of an Internet-based chemical collaboratory. This is based on an integration of a World-Wide Web server running the HTTP protocol, hypertext-markup language-based browsers, molecular visualizers based on Explorer EyeChem modules, and browsers implementing the virtual-reality modelling language 3D (VRML) scene description.

Virtual reality modeling language in chemistry.

A new concept in the field of molecular modeling using the information transfer mechanism of the World Wide Web (WWW) is presented. The Virtual Reality Modeling Language (VRML) provides an object-oriented method for the description of molecular models. The structure and capabilities of this new language are introduced. It is shown that the transport of molecular models over the WWW using VRML is a very efficient and powerful method for the exchange of molecular information.

The C23A: first step to a monitoring system of CELSS in flight.

Studies for every level of CELSS: Waste processing, food production, photosynthesis system, and so on ..., imply an automatic system to control, command and quantify gases, water and chemical compounds. Used for many years in plant physiology studies, the C23A system monitors the analysis and quantifies gases (O2, CO2. N2, ...), physical parameters (temperature, humidity, ...) and chemical compounds (NH4+, N03-, ...) on numerous experiments. In the new version, the architecture of the computing system is near of the space requirements. We have chosen a structure with three independent levels: acquisition, monitoring and supervision. Moreover, we use multiplexed analysers: IRGA, mass spectrometer and cheminal analyser. The multiplexing increases the accuracy of the measurements and could facilitate the spatialization. Thus the whole structure anticipates the entire separation between automation in space and control-command on ground.

HIPIN--a generic HIS/RIS-PACS interface based on clinical radiodiagnostic procedures.

Within the EurIPACS HIPIN topic a generic HIS/RIS-PACS interface will be designed, implemented and evaluated. It is generally agreed that integration with the HIS/RIS is essential for the acceptance of PACS in a clinical environment. An interface between HIS/RIS and PACS allows more efficient usage of both systems, better integration of data, better consistency checking on shared data and better security and error handling. Also the PACS performance is improved by using HIS/RIS information to steer the image migration within the PACS. In this paper the functional specifications of the interface are described. These specifications are based on descriptions of clinical radiodiagnostic procedures. The generic interface consists of a common part, and of site specific adapters. The common part is identical for all incarnations and performs message scheduling, processing and logging. The adapters are specific for each communication standard, e.g. ACR-NEMA or HL7, and for each hospital. The interface will be implemented at the radiology department of the Philipps University Hospital in Marburg (Germany) and at the orthopaedic and neuroradiology departments of the hospital of the Free University in Brussels (Belgium).

In-house access to PACS images and related data through World Wide Web.

The development of a hospital wide PACS is in progress at the University Hospital of Geneva and several archive modules are operational since 1992. This PACS is intended for wide distribution of images to clinical wards. As the PACS project and the number of archived images grow rapidly in the hospital, it was necessary to provide an easy, more widely accessible and convenient access to the PACS database for the clinicians in the different wards and clinical units of the hospital. An innovative solution has been developed using tools such as Netscape navigator and NCSA World Wide Web server as an alternative to conventional database query and retrieval software. These tools present the advantages of providing a user interface which is the same, independent of the platform being used (e.g. Mac, Windows, UNIX), and an easy integration of different types of documents (e.g. text, images). A strict access control has been added to this interface. It allows user identification and access rights checking, as defined by the in-house hospital information system, before allowing the navigation through patient data records.

Integration of a voice processor machine in a PACS.

The final stage of development of a clinical picture archiving and communication system (PACS) at the University of California at Los Angeles (UCLA) department of radiological sciences consists of building a documentation package of a complete radiological consultation. In this paper, we present the technological aspect of the integration of a digital voice server in our PACS environment. This component improves the timely delivery of the diagnostic report with the images. The interface of this voice system is integrated into the PACS display station. It offers the user the capability to easily dictate and/or listen to radiological reports, while viewing and/or performing image processing operations at the display station.

From multimodality digital imaging to multimedia patient record.

The constant improvement in computer power and performance nowadays offers convenient and efficient means of manipulating images, graphics, and movies on off-the-shelf workstations. With this improvement the trend toward integration of multimodality clinical documents from patient records comes naturally. Images and graphs are certainly the most important part of the complementary information that must accompany the text and numerical data. It is, however, possible to include sounds and voice messages together with all the other modalities. In medicine that could certainly help conveying hart murmur or sounds, but could also offer a convenient way of including vocal messages and comments. These new possibilities will certainly change the way physicians use workstations for direct communication. The computer industry will soon offer means of interactive communication between remote users through computer workstations. That alone will open a completely new era in cooperative computing and remote consultation scenarios in medicine. More than the technology itself, a complete change in behavior and work habits can be expected in the medical community.

Digital image management and communication in medicine.

With the rapid development of digital imaging modalities in medicine, there is an increasing need for an efficient management and archival of medical images in digital form. Picture Archiving and Communication Systems (PACS) are becoming an essential component of medical imaging equipment, allowing for medical images to be accessed and stored directly in digital form. This paper describes a hospital-wide PACS currently under development at the University Hospital of Geneva, based on an open architecture, regrouping equipment from different vendors in a distributed topology. The image archival is organized in multiple locations geographically distributed in the hospital. The PACS database is fully integrated with the concurrent Radiology Information System (RIS) and Hospital Information System (HIS). A standard image storage format called the PAPYRUS format was developed for the storage of medical images from a variety of imaging modalities. To provide a more uniform user interface on a variety of different workstations, a common platform for image display and manipulation called OSIRIS was developed.
