New Super Scanner Can Scan Body in Under a Minute
Smivs writes to mention that a new 3D scanner, unveiled at the Radiological Society of North America, has been in use for the last month at the Metro Health medical center in Cleveland, Ohio. This new scanner allows for much more detailed scans of the entire body in just under one minute also cutting the exposure to x-rays by as much as 80%. The cost of the new tech has not yet been released.
They now use Gamma rays......
I am the unwilling control for my Origin.
It's a CT scanner.
In other words, the technology is X-ray, but it electronically combines many images from many angles to build up a 3D image of what's inside the patient.
By the way, CT scans and MRIs are somewhat complementary to each other. Which one is "better" depends on what you are looking for:
CT uses X-rays, which I beleive (to my limited understanding) essentially measure density. Denser matter stops more X-rays, less dense matter lets more through.
MRI on the other hand uses magnetic resonance, which senses water concentration by alligning the magnetic dipole moments of water neuclei, and then "pinging" them and watching them resonate. Water concentration in the wrong place can indicate ruptured cell walls found in tumors, for example. Depending on exactly what you're hoping to spot, one may be better technology than the other.
