If you've ever been in a CT scanner, you were probably nervous. Did the scan produce the best and most accurate pictures of your insides so your doctors would form an accurate opinion about any conditions?

Most likely, your CT scan was used very well -- but the accuracy of those images sometimes comes into question. General Electric is trying to improve on this by releasing a new high-definition CT scanner.

This new scanner should produce clearer images while reducing your exposure to radiation at the same time. Just like x-rays, CT scans throw radiation through your body at the same time looking for maladies. Sounds like an oxymoron, right? It's one of the few ways a full-body, non-invasive look inside your body can be done with current techniques, though.
