Design and Implementation of Picture Archiving and Communication System Component in the Ubiquitous Environments

Objective: The recent medical treatment guidelines and the development of information technology make hospitals reduce the expense in surrounding environment and it requires improving the quality of rapid medical treatment. Moreover, MIS (Medical Information System) is evolved toward integration of medical IT and situation is changing with increasing high speed in the information communication technology convergence. Methods: PACS Component in the ubiquitous refers to construct mobile & wireless system of hospital which has constructed in network environment. Because of RFID (Radio Frequency Identification) development in existing system, every staff can log on easily to MIS whenever and wherever. In this paper, RFID server and tag manager modified patient tag that allocated patient information database server (tag UID, no, name, password) using UbiU 13.56MHz kit in the environment. Results: It is the main technology to implement automatic medical examination processing system. This paper provides a patient tag manager, PACS application component. In addition, designed and implemented database server's component server and mobile web server that recognized patient tag and medical data in the mobile environments. The component implemented client program of staff's PDA application that recognized medical data in the current server. The component decreased fewer patient examination time than conventional PACS, staff examined patient in the wards. This system implemented radiological information in the mobile module. Conclusion: This system implemented RFID patient card, and designed mobile PACS component that performed patient data based database environments, This component expanded PACS in the mobile web environment, and so reduced delay time of requisition, medical treatment, lab.
