The data formats and the communication protocols of Digital Imaging and Communication in Medicine (DICOM) Standard are defined based on the Object Oriented Analysis (OOA) of medical images in Radiological Information Systems (RIS) or Hospital Information System (HIS). At the first step in the design of a large scale software system, it is essential to analyze the real world entities in the domain of the problem. The OOA is one of a techniques for the analysis. In the OOA, entities are depicted as objects. An object has information and acts according to the information. The 00A depicts the structural relationships among the objects, the dependency of information contained by an object on that of another object, and interactions between the objects. With the better planning in the aid of OOA, we can construct the more useful RIS or HIS. This paper reviews the basic concepts of OOA for the better use of DICOM Standard and for the better planning of RIS/HIS based on DICOM.
