The role of digital imaging and communications in medicine in an evolving healthcare computing environment: the model is the message.

The decision to use Digital Imaging and Communications in Medicine (DICOM), Health Level 7 (HL7), a common object broker such as the Common Object Request Brokering Architecture (CORBA) or ActiveX (Microsoft Corp, Redmond, WA) or any other protocol for the transfer of DICOM data depends on the requirements of a particular implementation. The selection of protocol is independent of the information model. Our goal as message standards developers is to design a data interchange infrastructure that will faithfully convey the computer-based patient record and make it available to authorized health care providers when and where it is needed for patient care. DICOM accurately and expressively represents the clinically significant properties of images and the semantics of image-related information. The DICOM data model is small and well-defined. The model can be expressed in Standard Generalized Markup Language (SGML) or Object Management Group Interface Definition Language or other common syntax-and can be implemented using any reliable communications protocol. Therefore our opinion is that the DICOM semantic data model should serve as the basis for a logically equivalent set of specifications in HL7, CORBA, ActiveX, and SGML for the interchange of biomedical images and image-related information.

PACS/information systems interoperability using Enterprise Communication Framework.

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), 3) Interaction Model, and 4) Message Model. To realize this framework, a software component called the Enterprise Communicator (EC) is used. In this paper, we will demonstrate the use of the framework in interoperating a picture archiving and communication system (PACS) with a radiology information system (RIS).

MAGIC: an experimental system for generating multimedia briefings about post-bypass patient status.

We describe MAGIC, an experimental system for generating multimedia briefings about the clinical status of post-bypass patients entering a cardiac ICU. MAGIC is a distributed system whose components use knowledge-based techniques for planning and generating briefings in text, speech, and graphics. These briefings are coordinated together by reasoning with dynamically generated temporal and spatial constraints. Formative evaluation using system mock-ups with ICU nurses and residents have been used to determine the general format and content of these briefings. We present an overview of MAGIC's architecture and show what it can currently generate.
