The Digital Imaging and Communications in Medicine (DICOM) protocol is currently the ubiquitous standard for the communication of medical images and related data within the radiology department. However, seamless image distribution within the healthcare enterprise and especially with research and educational information systems is still hard to achieve, as software developers of such third-party applications have to go through the rather cumbersome task of adapting the DICOM communication model and implementing the DICOM protocol. This paper gives a brief outline of current trends in medical image distribution in the healthcare enterprise, and proposes a new technological approach for distributing DICOM images and related data through commonplace Internet technologies, based on the emerging web services software paradigm. In particular, the paper describes the DICOM Image Management (DIM) web service which acts as a façade for conventional DICOM sources allowing DICOM image data and related information, to be transformed into XML documents encapsulated in SOAP messages, enabling integration at the application level through general purpose standardized web technologies. Implementation issues are discussed and a demonstration of engaging the DIM web service is included.

    • "The service converts the received images back to the DICOM and forwards them to the intended device. Earlier projects like MammoGrid used this approach in their own middleware Alien (now included in gLite/EGEE-1), and also, more recently, others, i.e., Kaldouni et al. [21], [22]. DICOM gateways based on Web services have the advantage of using a standardized and proven technology for the grid transfer that is already deployed in grids based on the Globus toolkit version 3.0 or higher.

    ABSTRACT: Grid computing, the collaboration of distributed resources across institutional borders, is an emerging technology to meet the rising demand on computing power and storage capacity in fields such as high-energy physics, climate modeling, or more recently, life sciences. A secure, reliable, and highly efficient data transport plays an integral role in such grid environments and even more so in medical grids. Unfortunately, many grid middleware distributions, such as the well-known Globus Toolkit, lack the integration of the world-wide medical image communication standard Digital Imaging and Communication in Medicine (DICOM). Currently, the DICOM protocol first needs to be converted to the file transfer protocol (FTP) that is offered by the grid middleware. This effectively reduces most of the advantages and security an integrated network of DICOM devices offers. In this paper, a solution is proposed that adapts the DICOM protocol to the Globus grid security infrastructure and utilizes routers to transparently route traffic to and from DICOM systems. Thus, all legacy DICOM devices can be seamlessly integrated into the grid without modifications. A prototype of the grid routers with the most important DICOM functionality has been developed and successfully tested in the MediGRID test bed, the German grid project for life sciences.

    • "For radiological data discovery and retrieval, the authoring application exploits a modular, extensible, multilayer web services environment [22],[23]. At a first level, primary web services act as a wrapper to conventional DICOM image servers, and expose the principal DICOM services of query, retrieve, and store to any other software application or web service over the Internet, using standard XML documents communicated via SOAP messages.

    ABSTRACT: Teaching files serve the educational process in medicine and especially in the field of radiology in a variety of ways. The most common way is as peer-reviewed archival information resources used as a means for formal professional scientific communication. Only recently interest is shifting towards using digital teaching files to support the undergraduate medical educational process. This paper presents our approach to bridge and technologically integrate the educational environment, where clinical information is consumed, with the healthcare enterprise where clinical data is generated via a novel teaching file authoring environment that supports the creation of teaching files that can be viewed as individual learning modules and can be incorporated into generic learning management systems. I. INTRODUCTION here is currently an international trend to involve computers and the Internet in medical curricula as well in continuing life-long medical learning. This increasing employment of new technologies in higher medical education is also strongly related to an emerging trend in education that shifts attention from teaching to learning (1). Like many other cognitive domains, medical education can be considered in terms of three levels of increasing complexity and importance: information (i.e. simple facts), knowledge (i.e. information with a purpose), and understanding (i.e. conscious knowledge, achievement of explanation and grasp of reasonableness). Technology can

    ABSTRACT: Scenario has been largely used in design progression of different engineering disciplines, mostly in software engineering and Human-Machine Interaction. Scenario helps the software designers to border on the user and usage requirements. Although the design process in many fields of product engineering deals with tasks and functions, and step away from the final users, in medical and healthcare product design the understanding and specification of user requirements become an important issue. Thus, scenario can play an essential role as a tool for engineers to help them to identify and determine the usage of the medical devices. This paper investigates the use of scenarios in design development of healthcare products, and proposes a new concept of using scenarios in the evaluation phase of user dependent healthcare products. Our proposed model for scenario driven approach represents the confrontation between engineering (device design) and medical (usage), through the scenario specification. The new scenario specifies: cure procedure, device functions, usage situation and observation.
