Distributed Object Medical Imaging Model
Abstract- Digital medical informatics and images are commonly used in hospitals today,. Because of the interrelatedness of the radiology department and other departments, especially the intensive care unit and emergency department, the transmission and sharing of medical images has become a critical issue. Our research group has developed a Java-based Distributed Object Medical Imaging Model(DOMIM) to facilitate the rapid development and deployment of medical imaging applications in a distributed environment that can be shared and used by related departments and mobile physiciansDOMIM is a unique suite of multimedia telemedicine applications developed for the use by medical related organizations. The applications support realtime patientsâ data, image files, audio and video diagnosis annotation exchanges. The DOMIM enables joint collaboration between radiologists and physicians while they are at distant geographical locations. The DOMIM environment consists of heterogeneous, autonomous, and legacy resources. The Common Object Request Broker Architecture (CORBA), Java Database Connectivity (JDBC), and Java language provide the capability to combine the DOMIM resources into an integrated, interoperable, and scalable system. The underneath technology, including IDL ORB, Event Service, IIOP JDBC/ODBC, legacy system wrapping and Java implementation are explored. This paper explores a distributed collaborative CORBA/JDBC based framework that will enhance medical information management requirements and development. It encompasses a new paradigm for the delivery of health services that requires process reengineering, cultural changes, as well as organizational changes
On the Use of XML in Medical Imaging Web-Based Applications
The rapid growth of digital technology in medical fields over recent years has increased the need for applications able to manage patient medical records, imaging data, and chart information. Web-based applications are implemented with the purpose to link digital databases, storage and transmission protocols, management of large volumes of data and security concepts, allowing the possibility to read, analyze, and even diagnose remotely from the medical center where the information was acquired. The objective of this paper is to analyze the use of the Extensible Markup Language (XML) language in web-based applications that aid in diagnosis or treatment of patients, considering how this protocol allows indexing and exchanging the huge amount of information associated with each medical case. The purpose of this paper is to point out the main advantages and drawbacks of the XML technology in order to provide key ideas for future web-based applicationsPeer ReviewedPostprint (author's final draft
The Digital Anatomist Information System and Its Use in the Generation and Delivery of Web-Based Anatomy Atlases
Advances in network and imaging technology, coupled with the availability of 3-D datasets
such as the Visible Human, provide a unique opportunity for developing information systems
in anatomy that can deliver relevant knowledge directly to the clinician, researcher or educator. A software framework is described for developing such a system within a distributed architecture that includes spatial and symbolic anatomy information resources, Web and custom servers, and authoring and end-user client programs. The authoring tools have been used to create 3-D atlases of the brain, knee and thorax that are used both locally and throughout the world. For the one and a half year period from June 1995âJanuary 1997, the on-line atlases were accessed by over 33,000 sites from 94 countries, with an average of over 4000 ââhitsââ per day, and 25,000 hits per day during peak exam periods. The atlases have been linked to by over 500 sites, and have received at least six unsolicited awards by outside rating institutions. The flexibility of the software framework has allowed the information system to evolve with advances in technology and representation methods. Possible new features include knowledge-based image retrieval and tutoring, dynamic generation of 3-D scenes, and eventually, real-time virtual reality navigation through the body. Such features, when coupled with other on-line biomedical information resources, should lead to interesting new ways for
managing and accessing structural information in medicine
Web Services and IT Management in Healthcare and Grid Computing
Alma Ata Declaration on Primary Health Care defines , health as not just absence of disease but fitness at all levels i.e.Physically, mentally, Psychologically, spirtually, socially, and so on. RCH emphasizes fitness at all level along with health education and medical education. For the last one decade IT has contributed substantially in the healthcare domain. Tele-Medicine, Health informatics, using IT for Health for Prevention, curing, rehabilitation, Medical Education and accessing resources are the some of them.Web Services, IT Management, IT in healthcare, Health Informatics
A perspective on the Healthgrid initiative
This paper presents a perspective on the Healthgrid initiative which involves
European projects deploying pioneering applications of grid technology in the
health sector. In the last couple of years, several grid projects have been
funded on health related issues at national and European levels. A crucial
issue is to maximize their cross fertilization in the context of an environment
where data of medical interest can be stored and made easily available to the
different actors in healthcare, physicians, healthcare centres and
administrations, and of course the citizens. The Healthgrid initiative,
represented by the Healthgrid association (http://www.healthgrid.org), was
initiated to bring the necessary long term continuity, to reinforce and promote
awareness of the possibilities and advantages linked to the deployment of GRID
technologies in health. Technologies to address the specific requirements for
medical applications are under development. Results from the DataGrid and other
projects are given as examples of early applications.Comment: 6 pages, 1 figure. Accepted by the Second International Workshop on

Image database system for glaucoma diagnosis support
Tato prĂĄce popisuje pĆehled standardnĂch a pokroÄilĂœch metod pouĆŸĂvanĂœch k diagnose glaukomu v rannĂ©m stĂĄdiu. Na zĂĄkladÄ teoretickĂœch poznatkĆŻ je implementovĂĄn internetovÄ orientovanĂœ informaÄnĂ systĂ©m pro oÄnĂ lĂ©kaĆe, kterĂœ mĂĄ tĆi hlavnĂ cĂle. PrvnĂm cĂlem je moĆŸnost sdĂlenĂ osobnĂch dat konkrĂ©tnĂho pacienta bez nutnosti posĂlat tato data internetem. DruhĂœm cĂlem je vytvoĆit ĂșÄet pacienta zaloĆŸenĂœ na kompletnĂm oÄnĂm vyĆĄetĆenĂ. PoslednĂm cĂlem je aplikovat algoritmus pro registraci intenzitnĂho a barevnĂ©ho fundus obrazu a na jeho zĂĄkladÄ vytvoĆit internetovÄ orientovanou tĆi-dimenzionĂĄlnĂ vizualizaci optickĂ©ho disku.

According to the theoretical knowledge, a web based information system for ophthalmologists with three main aims is implemented. The first aim is the possibility to share medical data of a concrete patient without sending his personal data through the Internet. The second aim is to create a patient account based on a complete eye examination procedure. The last aim is to improve the HRT diagnostic method with an image registration algorithm for the fundus and intensity images and create an optic nerve head web based 3D visualization. This master thesis is a part of project based on DAAD co-operation between Department of Biomedical Engineering, Brno University of Technology, Eye Clinic in Erlangen and Department of Computer Science, Friedrich-Alexander University, Erlangen-Nurnberg.
