Design And Application On Picture Archiving And Communication System

To meet the networking requirement of the heave data flow, load balance, and potential networking storm during expanding the application of PACS. To demonstrate the contribution of the PACS to various aspects of a hospital operating methods, management and services by the establishment and application of the large-scale PACS system. To demonstrate the contribution of the PACS to various aspects of a hospital operating methods, management and services by the establishment and application of the large-scale PACS system .Intel Net Structure 480T Giga Switch was used as main switch and connected to each building by optical channel at 1 Giga speed archive 100 MB/s to each port. At the same time, the in dependence of the original networking construction was physically kept. The layer 3 and 4 switchers was used as load balance to reduce the heavy load of the networking, and all the cabling for PACS used the super CAT5 along with the Intel Net Structure 1520 to prepare for the potential networking storm. To integrate all modalities no matter whether in DICOM or not into PACS to storage whole images and share those resources. Setup traditional PACS to integrate all modalities which is based on. Windows NT and SQL7.0 to store all kind of patients image files, all the clinical workstation can views those images by web, those license is up to 100 and in the systems, we built RAID 5 online HDD which has the capability to store images for 3 months and DLT long term archive storage up to 7T in size. PACS already finished the integration with RIS , HIS to expand images to whole hospital and ready to be a imaging center of one area. The comparison of various parameters and factors before and after the establishment and application of the PACS was conducted after statistic Analyses of the diagnostic workload/non-diagnostic workload ratio, the percentage of the traceable scientific data, the x-ray film retrievals, unit service cost and the patients' waiting duration and etc. in the hospital.An advanced intranet was set up to fully meet the high standard requirement of PACS. The good foundation for upgrading the whole networking 1 Giga application was build for realized share and transmission of image, information , and patient data within the hospital. The base of established for the standardized management of the hospital. Founded typical PACS ,connected hospital equipment at present ,realized primary no-film mode in department of radiology, PACS extended whole hospital clinical room, surgery, emergency treatment room etc,as well as realize PACS and HIS, some otherhospital networks connecting, established the center of image data, realized connecting the center of image data together with current area and other area hospitals, good easiness to use, convenience the doctor ,improved work efficiency. After the establishment of PACS, the emergency imaging examination time reduced by 64% in average; the data saving percentage exceeded 90%; the time of reporting greatly decreased; the film consumption decreased by 33%; the efficacy of images retrievals increased by 95%; and there were improvements at different degrees in many other aspects. The comparison of various parameters and factors before and after the establishment and application of the PACS was conducted after statistic Analyses of the diagnostic workload/non-diagnostic workload ratio, the percentage of the traceable scientific data, the x-ray film retrievals, unit service cost and the patients' waiting duration and etc. in the hospital.Good planning is the 1st step in setting up PACS and the equipment are the platform to ran PACS and all kinds of HIS. The networking construction is the foundation of e-hospital. Practice proved, current project related PACS planning as a whole practice in step by step is viable and successful. It is very important to establish a PACS system that will meet the practical requirements of a hospital, therefore, the system will play a positive promoting role in the improvement of the hospital operating procedure and management and all...
