The impact of image storage organization on the effectiveness of PACS.
Picture archiving communication system (PACS) requires efficient handling of large amounts of data. Mass storage systems are cost effective but slow, while very fast systems, like frame buffers and parallel transfer disks, are expensive. The image traffic can be divided into inbound traffic generated by diagnostic modalities and outbound traffic into workstations. At the contact points with medical professionals, the responses must be fast. Archiving, on the other hand, can employ slower but less expensive storage systems, provided that the primary activities are not impeded. This article illustrates a segmentation architecture meeting these requirements based on a clearly defined PACS concept.
