The standard format for medical imaging storage and transmission is DICOM. openEHR is an open standard
specification in health informatics that describes the management and storage, retrieval and exchange of health data in
electronic health records. Considering that the integration of DICOM and openEHR is beneficial to information sharing,
on the basis of XML-based DICOM format, we developed a method of creating a DICOM Imaging Archetype in
openEHR to enable the integration of DICOM and openEHR.
Each DICOM file contains abundant imaging information. However, because reading a DICOM involves looking up the
DICOM Data Dictionary, the readability of a DICOM file has been limited. openEHR has innovatively adopted two level
modeling method, making clinical information divided into lower level, the information model, and upper level,
archetypes and templates. But one critical challenge posed to the development of openEHR is the information sharing
problem, especially in imaging information sharing. For example, some important imaging information cannot be
displayed in an openEHR file. In this paper, to enhance the readability of a DICOM file and semantic interoperability of
an openEHR file, we developed a method of mapping a DICOM file to an openEHR file by adopting the form of
archetype defined in openEHR. Because an archetype has a tree structure, after mapping a DICOM file to an openEHR file, the converted information is structuralized in conformance with openEHR format. This method enables the
integration of DICOM and openEHR and data exchange without losing imaging information between two standards.
