Web-based image distribution performs well even with 16 concurrent personal computers (PCs). A 100-Mbit/s network and lossless compression are recommended for optimal performance, avoiding slow 10-Mbit/s connections and lossy compression.

Area of Science:

  • Medical Imaging
  • Computer Science
  • Network Performance

Background:

  • Web-based image distribution is crucial for modern healthcare.
  • Optimizing image download times is essential for efficient clinical workflows.

Purpose of the Study:

  • To evaluate web-based image distribution performance under concurrent download conditions.
  • To identify key server hardware and configuration factors impacting image download speed.

Main Methods:

  • Utilized custom software to measure time-to-display (TTD) for various image types.
  • Tested performance with up to 16 concurrent personal computers (PCs).
  • Varied server configurations including processor, RAM, network speed, and compression type.

Main Results:

  • TTD increased linearly with concurrent PCs but generally stayed below 5 seconds.
  • 10-Mbit/s network connections and lossy compression significantly increased TTD.
  • Higher network speeds (100/200 Mbit/s) and lossless compression yielded better performance.
  • Processor and RAM had minor impacts, except for computed radiography (CR) images with reduced RAM.

Conclusions:

  • Standard servers offer adequate performance for 16 concurrent clients.
  • A 100-Mbit/s network connection and lossless compression are highly recommended.
  • Avoid on-demand lossy compression in local area networks for better efficiency.
