ABSTRACT
Hospital image information system is evolving from department-oriented to patient-oriented. This paper introduces the implementation of Beijing University People's Hospital image data center. The ideas, approaches and the technological standards for image data center's system integration are proposed. Additionally, the problems in practical application and the outlook for this system are discussed.
ABSTRACT
Objective To realize information sharing and medical resources integration in different medical enterprises.Methods In accordance with IHE XDS-I image data registration-distribution model,regional data exchange center was set up so that the medical images and report data could be exchanged and shared,and the regional medical network could be smoothly upgraded in interconnection.Results Exchange and sharing of medical images and reports were realized.Standard IHE data interface was prepared for future images exchange between different hospitals.XDS-I model in domestic hospitals were put into practice.Conclusion The structure design of data center is feasible,reliable and effective.
ABSTRACT
The purpose of this study was to evaluate the migration of medical image data stored thorough mini-PACS to full-PACS at Yonsei University Medical Center (YUMC). The image data to be migrated were 2.7 TB stored through approximately 4,500 CD archives at Yongdong Severance hospital and 4.7 TB (2:1 compression) stored through 196 digital linear tape (DLT) archives at Severance hospital. Prior to carrying out the migration, principles, methods and expected practical affairs for the migration were discussed and planned to optimize the migration work by considering the cost and the effectiveness of migration work. Migration gateway workstations were set up and a migration software tool was developed. Real migration works were performed based on the results of several migration simulations. Severance hospital decided to migrate all stored image data. The CD image data of 2.7 TB were estimated total 2,250 hr (about 94 days) migration time, but the practical migration work was completed within 3 months by using maximum 5 workstations. The DLT data of 4.7 TB were estimated total 100 days migration time by applying 16 hr working time per day with single workstation, however, the practical migration work was taken 5 months. Meanwhile, 20% of the DLT image data were not able to migrate because the DLT were partially damaged due to frequent access. In conclusion, a migration plan should be carefully prepared by considering the individual hospital environments because the server system, archival media, the network, and the policy of data management may be unique.
