Paper Abstract

The ACR-NEMA 2.0 standard has made important strides toward providing a manufacturer- independent interconnection for PACS systems. The DICOM standard now in preparation takes an object-oriented approach to design of software protocols for data base query and image exchange. We have developed an object-oriented class library for accessing an ACR- NEMA 2.0 data dictionary and building ACR-NEMA formatted messages. The library, implemented in both Smalltalk/V and being implemented in C++, provides access to the entire ACR-NEMA 2.0 Data Dictionary and allows a program written in either language to ascertain required fields in messages, default values and allowable values of enumerated value elements. The design of the class hierarchies in the data dictionary is discussed in terms of the ACR-NEMA 2.0 standard and the integration of this design into the DICOM standard. Building a sample SEND_REQUEST message for image transfer is illustrated.
