Radiology Transmission on IRHN

As rural hospitals and clinics increase their diagnostic tools, the speed with which diagnostic images and data can be transmitted to specialists becomes increasingly important. According to the Health Care section of the National Broadband Plan, here are data file sizes for two widely used applications:

  • Mammography study (4 images) - 160 Megabytes
  • 64-slice CT scan - 3,000 Megabytes

Elapsed Time for Transmission:

Shown below are the time frames to transmit each type of file over a T1 circuit (commonly used by rural hospitals), as compared to using the IRHN, at either the 100Mbps rate, or the 1 Gbps rate:

  • Mammography study on T1 (1.5Mbps) - 14 minutes, 29 seconds
  • Mammography study on IRHN (100Mbps) - 16 seconds
  • Mammography study on IRHN (1 Gig) - 1 second
  • 64-slice CT scan on T1 (1.5Mbps) - 4 hours, 38 minutes, 10 seconds
  • 64-slice CT scan on IRHN (100Mbps) - 4 minutes, 50 seconds
  • 64-slice CT scan on IRHN (1 Gig) - 29 seconds
