The Bottom Line: The GE LightSpeed 16-slice has features that separate itself from the Philips product. GE has a higher Kw rating (100) and mA (800). The GE also offers a higher scan at 120 seconds, compared to Philips’ at 100 seconds. However, the Philips Brilliance 16 system is much more affordable, possibly saving someone around 20 to 30% compared to the GE unit. If these differences, features or any other items on this comparison chart do not make a difference for your specific application, then the Philips system may prove to be a scanner that will fall within your price range.
