Achieving Exponential Gains in Imaging Speed

A Dicom Systems and Pure Storage White Paper

Dicom Systems and Pure Storage conducted testing to evaluate if high-performance data storage affects medical image transmission latency and transfer speed. The testing focused on the routing functionality of the Dicom Systems Unifier enterprise imaging platform.
We tested various workflow functions including but not limited to Unifier DICOM routing and tag morphing, supported by Pure Storage(R) hardware. Our goal was to confirm if transmission time and transfer speed correlated with storage performance. Measurements included large, regular, and small DICOM studies. We tested a maximum throughput of 1,280 megabytes (MB) and assessed I/O performance and latency.
