Philips unveiled a new ultra-high-res 256-slice CT scanner called the Brilliance iCT at the Radiological Society of North America yesterday, a unit the company says not only produces higher quality 3D images using less radiation than previous scanners, but does it far more quickly -- a full body scan takes only a minute. The speedup is achieved because the rotating X-ray element spins some 22 percent faster than other models, hitting four revolutions a second at top speed. Getting in and out of the machine that much faster also cuts radiation exposure some 80 percent from a traditional X-ray machine, and Philips says the machine is accurate enough to capture a complete image of the heart in less than two beats. Metro Health in Cleveland is the first off the line with the new gear -- check the read link for a video of it in action.
