Research On DICOM Enhanced Information Objects And Their Applications

In last decade, with the adoption of new multi-frame mechanism, a series of new enhanced information objects (EIOs) were defined in DICOM, which are of more advantages than former information objects. They could support state-of-the-art medical imaging technologies and advanced clinical applications, also make the implementation process of their applications easier. The entity-relationship model has been modified in EIOs, which enables the capability to represent complex imaging environments, improves the effectiveness of image data communication and applications. While if systems could support the utilization of EIOs, they are of no doubt to be more effective for the image-based clinical diagnose and therapy.The dissertation has mainly discussed the following aspects:A) Review the evolution of medical imaging technologies and clinical applications which may correspondingly urge IODs to be outdated and their redefinition; further discuss the necessary of EIOs.B) Through the comparison of enhanced and original information objects, and the analysis of the relationship among EIOs, imaging and applications, the conclusive common and individual characteristics has been provided.C) Research on EIOs-based applications from the aspects of medical image data exchange, archiving and management, as well as its display and processing.D) Take PACS as typical example, extend the system based on EIOs common characteristics, and verify the advantages of the EIOs application value for current information systems.The main topic of this dissertation is to analysis the formation and new characteristics of EIOs, and to value EIOs' high application advantages in extending medical information systems and improving their performance. This work can serve as a guideline for the application of EIOs, an important part of DICOM.
