Service-oriented PACS-grid

Abstract

In clinical engineering, computerization of medical devices and chronic condition cares are becoming important [1]. Also, these two trends are heading to be converged. Thus, many of researches are being conducted to follow these trends globally. In treating chronic condition care, method to integrate information, such as imaging, hospital information, clinician’s reports, and others, in terms of target condition is considered as one of the applications for diagnosis importantly. The integrated information is yielded from diverse medical information devices. Thus, to do satisfy the trends, the methods to integrate medical information for chronic condition care and to integrate medical devices should be deliberated in the same line. Despite the converging trends, the previous research is not concerned. In this thesis, we discuss how to meet these requirements of visualization for chronic condition care and information integration with diverse medical devices such as existing PACS-Grid [2]; especially how to integrate diverse application into a platform, and how to accelerate platform performance derived from service-oriented applications. To do that, we reviewed previous works, such as existing PACS-Grid, TimeLine, and Sakura-Viewer. Then, we derived their characteristic services and we defined the services for medical application oriented to chronic condition care, and designed a service workflow for visualization of integrated information with Petri-net model [35]. Also, we proposed service virtualization framework for optimizing performance of platform. Finally, we handled several experiments, deduced from a clinical scenario, to show the usefulness of our proposed Service-oriented PACS-Grid. Through the results of the experiments, we can see that the Service-oriented PACS-Grid is useful and effective for supporting composite services in the platform and service both sides.
