Design and optimizing factors of PACS network architecture / 中华放射学杂志

ABSTRACT

Objective Exploring the design and optimizing factors of picture archiving and communication system (PACS) network architecture. Methods Based on the PACS of shanghai first hospital to performed the measurements and tests on the requirements of network bandwidth and transmitting rate for different PACS functions and procedures respectively in static and dynamic network traffic situation, utilizing the network monitoring tools which built in workstations and provided by Windows NT. Results No obvious difference between switch equipment and HUB when measurements and tests implemented in static situation except router which slow down the rate markedly. In dynamic environment Switch is able to provide higher bandwidth utilizing than HUB and local system scope communication achieved faster transmitting rate than global system. Conclusion The primary optimizing factors of PACS network architecture design include concise network topology and disassemble tremendous global traffic to multiple distributed local scope network communication to reduce the traffic of network backbone. The most important issue is guarantee essential bandwidth for diagnosis procedure of medical imaging.
