The DICOM standard, in addition to resolving certain problems with the ACR-NEMA 2.0 standard regarding network support and the clinical data dictionary, added new capabilities, in the form of study content notification and patient, study and results management services, intended to assist in interfacing between PACS and HIS or RIS systems. We have defined and implemented a mechanism that allows a DICOM application entity (AE) to interrogate an HL7 based RIS using DICOM services. The implementation involved development of a DICOM- HL7 gateway which converted between DICOM and HL7 messages to achieve the desired retrieval capability. This mechanism, based on the DICOM query/retrieve service, was used to interface a DeJarnette Research film digitizer to an IDXrad RIS at the University of Maryland Medical Systems hospital in Baltimore, Maryland. A C++ class library was developed for both DICOM and HL7 massaging, with several constructors used to convert between the two standards.© (1995) COPYRIGHT SPIE--The International Society for Optical Engineering.
