2 TB and growing fast: 18 months of experience with the Innsbruck PACS

Zusammenfassung

Since 1997, the Innsbruck PACS system has been drastically expanded from its initial setting in the Traumatology Department. Currently, five phosphor plate systems, four CT systems, two MRI systems, three angiography units, two fluoroscopy units, three ultrasound systems, one film digitizer and several C-arms in the operating rooms are connected to the PACS, resulting in around 8 GB of losslessly compressed imaged data to be archived each working day. The total amount of losslessly compressed data stored in the archive amounts to some 2.2 TB as of March 1999. This huge data volume and the growing number of viewing stations connected have demanded a re-design of several of the PACS archive system components. A powerful high-availability central database system and a scalable cluster of file servers have been established to guarantee fast data access, and efforts are currently underway to replace the initially adopted CD-R jukeboxes by a powerful and expandable tape archive system as the long-term image archive
