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 Wilsonin the end, I dont think its a big deal.11/24/2014 - 8:44pm
WonderkarpRight, I'm not going to argue with Black Manta. I've already argued once today on the Internet. Thats one time too many. Anybody hear about the Star Wars Spinoff news?11/24/2014 - 8:43pm
black mantaIf it's imprtant at all.11/24/2014 - 8:43pm
black mantaI'm with Andrew. I fail to see how this really improves anything. The importance of this is overstated.11/24/2014 - 8:42pm
Matthew Wilsonit should be obvious what those links are, but more transparency is never a bad thing in my eyes.11/24/2014 - 8:42pm
Wonderkarpyeah.11/24/2014 - 8:41pm
black mantaAll I see is GG ruining everything it touches in the name of some misguided and twisted notion of "ethics."11/24/2014 - 8:41pm
Andrew EisenWell, unless this was something the FTC was already working on. And still, it remains to be seen what its guideline updates actually say.11/24/2014 - 8:40pm
Wonderkarpand other media I suppose11/24/2014 - 8:39pm
WonderkarpI repeat, Its concidered a victory because, if its true, then it shows they are causing change in (Changes) Journalistic Practices in Games Media.11/24/2014 - 8:38pm
Wonderkarpits not the easiest "Ethical Issue" to discuss. Its more trivial. I'm playing devils advocate on this one.11/24/2014 - 8:36pm
black mantaEthics in what? Advertising? All you're doing is needlessly complicating things. There's no "victory" in that.11/24/2014 - 8:35pm
WonderkarpIts just a article's title. Its concidered a victory because, if its true, then it shows they are causing change in ethics. We were discussing those ethics11/24/2014 - 8:33pm
Andrew EisenNot knowing what cards a retailer accepts beforehand can be a headache. Not knowing the site you came from to purchase a good gets a small percentage of the sale? I'm not seeing it.11/24/2014 - 8:32pm
black mantaFurther evidence that shows just how horribly misguided this movement is.11/24/2014 - 8:30pm
black mantaSorry, no. A little blurb stating the obvious is hardly a major "victory."11/24/2014 - 8:29pm
WonderkarpI went to Costco on saturday, new costco, to sign up. and at the very end right before the membership, right as I'm swipping the card, they tol dme they only accept Amex...A little Disclosure helps11/24/2014 - 8:24pm
Wonderkarpand it just feels like having that disclosure somewhere will avoid headaches.11/24/2014 - 8:23pm
Wonderkarpyep. alot of people are very ignorant and look at life as black and white and are naive.11/24/2014 - 8:22pm
Andrew EisenThat's what I'm asking though. Are there a significant number of people that don't realize that's what happens when you buy the product through that link?11/24/2014 - 8:20pm
