Abstract

Multimodal PACS or high performance teleradiology systems require high throughput in order to be productive. Acquisition and availability of data and on-line storage capacity are significant factors for evaluating the acceptability of a PACS or teleradiology system in a clinical environment. Digital medical images contain an enormous amount of data. For example, a computed radiography image (2048 X 2048 X 10-bit) is composed of 8 megabytes (8-bit boundaries) of digital data. A CT examination consisting of 64 one-half megabyte images (512 X 512 X 12-bit) is composed of 32 megabytes (8-bit boundaries). The overall throughput of these systems is impacted by the protocol overhead, data collisions network media, and the I/O speed of the computer's disk system. This paper addresses I/O bandwidth, capacity, and data integrity of the disk storage system and specifically how parallel disk array implementations can be utilized in a PACS or teleradiology environment to improve throughput.
