Implementing a full-feature PACS solution in accordance with the IHE technical framework
Academic Radiology, 2004
Rationale and Objectives. During the last 4 years, Integrating the Healthcare Enterprise (IHE) has worked in establishing a reliable integrated environment for medical imaging devices and other clinical information systems by using existing industry standards such as Digital Imaging and Communication in Medicine (DICOM) and Health Level Seven (HL7). Because IHE is organized and driven by professional organizations representing both buyers and vendors, it was able to define a common language for the various health care parties who are involved in the integration process. Thus IHE offers a rigorously organized technical framework that provides a comprehensive guide for a coordinated implementation of information standards. Materials and Methods. A multistage plan for incorporating the IHE elements while scaling up general-purpose workstations with teleradiology functionalities to a full-feature picture archiving and communication system (PACS) solution was created. To introduce a pragmatic example, the plan approach was applied to the CHILI workstations (CHILI, Heidelberg, Germany). To implement the proposed plan in making various legacy systems comply with IHE, the effects of available resources and market needs on the plan are discussed. Most implementation challenges and problems were overcome using generic design approaches and well-designed DICOM utilities. Results. On completion of the first stage, the PACS viewer and reporting workstations were IHE-compliant. In addition, the plan facilitates the conformance process while maintaining the planned software development cycle. Conclusion. Based on these positive results and the practical experience acquired during the first stage, further stages will be completed to provide the system with the required plug-and-play interoperability among systems from different vendors.

System Health Level 7 (HL7) Clinical Document Architecture DICOM WADO a b s t r a c t Purpose: Integration based on open standards, in order to achieve communication and information interoperability, is one of the key aspects of modern health care information systems. However, this requirement represents one of the major challenges for the Information and Communication Technology (ICT) solutions, as systems today use diverse technologies, proprietary protocols and communication standards which are often not interoperable. One of the main producers of clinical information in healthcare settings represent Radiology
Standardization and Interoperability: Basic Conditions for Efficient Solutions
IFMBE Proceedings, 2011
Information and communication technologies have already become inseparable part of healthcare sector activities. In the paper we discuss the issues of standardization and interoperability that are crucial for correct interconnection of medical and other devices and information systems. Our previous work in the area has led us to the conclusion that successful integration of partial solutions will be strongly dependent on the issue of interoperability of medical devices and information systems. It comprises problems of standardization of data acquisition, communication, processing, and storage; and connected problem: correct data mapping between different ICT applications.

A successful PACS (Picture Archiving and Communications System) implementation requires an eclectic integration of a number of key technologies. Among these are equipment interfaces, communications, storage, and display. Coincident with this, the software architecture must support a distributed system of heterogeneous structures, provide for protocol and format conversions to a unified system standard, be scalable to accommodate expansion, and provide a measure of fault tolerance. In this paper we survey the current state of the UCLA PACS components and architecture.
PACS/information systems interoperability using Enterprise Communication Framework
IEEE Transactions on Information Technology in Biomedicine, 1998
Interoperability among healthcare applications goes beyond connectivity to allow components to exchange structured information and work together in a predictable, coordinated fashion. To facilitate building an interoperability infrastructure, an Enterprise Communication Framework (ECF) was developed by the members of the Andover Working Group for Healthcare Interoperability (AWG-OHI). The ECF consists of four models: 1) Use Case Model, 2) Domain Information Model (DIM),
Problems with integrating legacy systems.

Abstract The economic and organizational impact of imposing state-of-the-art technology to the large number of proprietary legacy systems operational in most hospitals requires integrated clinical professional workstations to provide flexible encapsulation mechanisms for these systems rather than reengineering these systems to this new technology. In this paper the implications of different input/output and translation models of legacy systems for their integration into a clinical workstation is described.

Every single piece of healthcare information should be fully integrated and transparent within the electronic health record. The Italian Hospital of Buenos Aires initiated the project Multimedia Health Record with the goal to achieve this integration while maintaining a holistic view of current structure of the systems of the Hospital, where the axis remains are the patient and longitudinal history, commencing with section Computed Tomography. Was implemented DICOM standard for communication and image storage and bought a PACS. It was necessary adapt our generic reporting system for live up to the commercial RIS. The Computerized Tomography (CT) Scanners of our hospital were easily integrated into the DICOM network and all the CT Scans generated by our radiology service were stored in the PACS, reported using the Structured Reporting System (we installed diagnostic terminals equipped with 3 monitors) and displayed in the EHR at any point of HIBA's healthcare network.
An open test bed for medical device integration and coordination
2009 31st International Conference on Software Engineering - Companion Volume, 2009
Medical devices historically have been monolithic units -developed, validated, and approved by regulatory authorities as stand-alone entities. Modern medical devices increasingly incorporate connectivity mechanisms that offer the potential to stream device data into electronic health records, integrate information from multiple devices into single customizable displays, and coordinate the actions of groups of cooperating devices to realize "closed loop" scenarios and automate clinical workflows. However, it is not clear what middleware and integration architectures may be best suited for these possibly numerous scenarios. More troubling, current verification and validation techniques used in the device industry are not targeted to assuring groups of integrated devices, and regulatory regimes have not yet been developed that allow manufacturers to bring systems of cooperating devices (each approved individually beforehand) to market.

Commercial telemedicine systems are increasingly functional, incorporating video-conferencing capabilities, diagnostic peripherals, medication reminders, and patient education services. However, these systems (1) rarely utilize information architectures which allow them to be easily integrated with existing health information networks and (2) do not always protect patient confidentiality with adequate security mechanisms. Using object-oriented methods and software wrappers, we illustrate the transformation of an existing stand-alone telemedicine system into 'plug-and-play' components that function in a distributed medical information environment. We show, through the use of open standards and published component interfaces, that commercial telemedicine offerings which were once incompatible with electronic patient record systems can now share relevant data with clinical information repositories while at the same time hiding the proprietary implementations of the respective s...
