Popis: The DICOM standard has established itself successfully in the PACS world. Practice has shown, however, that interoperability of DICOM devices cannot be taken for granted. Many devices only support a subset of the capabilities and options of the DICOM services they claim to support - and even that sometimes in a non-conforming manner. This issue is only partly addressed by the concept of the DICOM conformance statement which describes the services, options and features supported by an implementation and allows an expert to assess whether two DICOM implementations are likely to interoperate. We propose a new approach that can be understood as a step towards an 'automated' conformance statement. The 'Description Notation' for Interoperability Assessment' (DeNIA) allows to formally describe the data structures sent or received by a DICOM implementation. An evaluation tool reads two of these models and automatically derives a conclusion whether or not the two systems can successfully exchange messages and whether all messages created by the sender can be understood by the receiver. DeNIA allows to explicitly describe the capability of a receiver to 'gracefully' accept certain deviations from the standard -- a capability which accounts for much of the interoperability found in DICOM systems today.© (2002) COPYRIGHT SPIE--The International Society for Optical Engineering.
