GE Lightspeed Ultra 8-Slice vs. Brightspeed Edge 8-Slice

Featured Image


On the surface, the LightSpeed Ultra 8 and the BrightSpeed Edge have a lot in common. Both CT scanners come from GE, both scan at 8 slices, and there's a significant overlap in their years of production. So what exactly are the differences that make these systems unique from one another?

LightSpeed Ultra 8 vs BrightSpeed Edge: the Biggest Differences

Tube Size

Without a doubt, the most important difference between the Ultra 8 and the Edge is the standard X-ray tube size. The Ultra 8 comes standard with a 6.3 MHU tube while the Edge comes with a 3.5 MHU tube. The Edge is available in a 6.3 configuration as an option.

This difference in tube size impacts the throughput capacity of the system as well as the image clarity in larger, heavier patients. A system with a 6.3 MHU tube will be much better suited for a high-traffic facility or a facility that specializes in bariatric studies. The 3.5 MHU version of the Edge would be a better pick for a facility that sees fewer patients for CT studies.


The Edge is designed with a smaller footprint than the Ultra 8, meaning It can be installed in a smaller space. This is another feature that makes the Edge a compelling option for smaller, lower-traffic facilities.

For quick reference on several other differences between these two models, take a look at the table below:

Lightspeed Ultra 8 Brightspeed Edge
2002 and newer 2005 and newer
6.3 MHU tube 3.5 MHU tube or 6.3 MHU option
Octane or Xtream console Xtream console
53 - 60 kW generator 36 - 60 kW generator

Ultimately, the choice between these two comes down to the specific circumstances of your facility. Patient traffic, specialty, and space constraints could all play a role and there are scenarios where either will shine.
