Abstract:
Objective:To explore the application of three-level storage pattern(on-line,near-line,off-line)to picture archiving and communication system(PACS),and to find a solution to the long-term storage of medical imaging data in PACS of the basic unites.Methods:To realize the on-line storage of medical imaging data by the redundant array of independent disk(RAID)of host-server;To realize the near-line storage of medical imaging data by the network attached storage(NAS);To realize the off-line storage of medical imaging data by the tape-drive.Results:The long-term storage of medical imaging data in PACS has been available in our hospital for one year since the three-level storage pattern used in PACS.It not only realizes the on-line access of enormous amount of medical imaging data,but also protects the imaging data's integrity when the on-line data damaged by human's activities or fire,etc.Conclusion:The application of three-level storage pattern in PACS,which is characterized as low expense,dependable performance,simple maintenance,can become perfect pattern in the basic Level hospital.
