Game Tech Could Help Reduce CT Scan Radiation Levels

July 15, 2010 -

A breakthrough in CT (Cat) scan reconstruction technology that utilizes graphic processing (GPU) units could lead to lower amounts of radiation being absorbed by patients undergoing cone beam CT scans.

Previous attempts at (essentially) turning down the radiation emitted during a CT scan (by “reducing the total number of X-ray projections and the mAs level per projection“) resulted in “mathematically incomplete data” that took hours to process. Researchers from the University of California, San Diego, however, have developed a CT reconstruction algorithm that processes data in parallel, turning the process into a two-minute task.

Lead Author Xun Jia reported that reconstruction time ranged from 77 to 130 seconds when using an NVIDIA Tesla C1060 GPU card, which he estimated was 100 times faster than similar reconstruction approaches.

"With our technique, we can reconstruct cone beam CT images with only a few projections -- 40 in most cases -- and lower mAs levels," Jia stated. "This considerably lowered the radiation dose."

Senior Author of the study Steve Jiang added, “CT dose has become a major concern of medical community. For each year's use of today's scanning technology, the resulting cancers could cause about 14,500 deaths.

The researchers will discuss their findings at next week’s annual meeting of the American Association of Physicists in Medicine (AAPM) in Philadelphia.

So Nvidia cures cancer, does ATI kick puppies?  ;)

Matthew Wilson@mach no way in hell, so that is why I want them to stay away.03/26/2015 - 7:21pm
MechaCrash"Get the movie right" is preferable to "stay away," but do you really think they won't screw it up?03/26/2015 - 7:19pm
Craig R.And yes, 90's games. Damn near all of my fav computer & console games were from that decade03/26/2015 - 7:00pm

ConsterApparently Salesforce and the NCAA are also upset over SB 101. I know they're not video-games related, but maybe add a line to the article?03/26/2015 - 2:54pm
Andrew EisenThat said, I doubt that if the movie gets made, it will be similar to either version of the show. But, Star Wars movies will be out again and the designs are still pretty awesome so it's got a chance.03/26/2015 - 2:34pm

Matthew Wilson@AE I am kinda surprised sony would want to make a movie of something that is 30 years old. I woulder how many people remember robotech?03/26/2015 - 2:24pm
Andrew EisenProbably not but my wish is that Hollywood make good anime movies.03/26/2015 - 2:20pm
Matthew Wilsonhttp://variety.com/2015/film/news/robotech-movie-sony-tv-series-anime-1201460191/ am I the only one that wishes Hollywood would stay a million mile away from anime?03/26/2015 - 1:29pm
