"A new scanner has been unveiled which can produce 3D body images of unprecedented clarity while reducing radiation by as much as 80%."
The new 256-slice CT machine takes large numbers of X-ray pictures, and combines them using computer technology to produce the final detailed images.
It also generates images in a fraction of the time of other scanners: a full body scan takes less than a minute.
The Philips machine was unveiled at the Radiological Society of North America.
Because the images are 3D they can be rotated and viewed from different directions - giving doctors the greatest possible help in looking for signs of abnormalities or disease.
All images also can be accessed on any computer in a hospital or by colleagues and researchers remotely, to make it easier for the whole team to share information.
The scan is much quicker than current technology, as the machine's X-ray emitting gantry - the giant ring-shaped part that surrounds the patient - can rotate four times in a single second - 22% faster than current systems.
