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?  ;)

Andrew EisenMarvel has replaced Manara on the variant covers for Thor #2 and Avengers and X-Men: AXIS #1. I hope I'm wrong but I don't think Marvel is learning the right lesson here.09/23/2014 - 6:26pm
quiknkoldI'm 7 years old, and my cousin(Also 7, maybe 8 at this time) tells me has Battletoads. its Summer Vacation. We play and play and play until finally, We won coop. Those were the days.09/23/2014 - 5:29pm
quiknkoldlets take a moment to share some gaming memories, shall we?09/23/2014 - 5:28pm
MechaTama31I buy stuff off the eshop because it gives me the convenience of a flashcart without the guilt.09/23/2014 - 5:03pm
Montewell thanks for the info Eisen; try that the next time i need something off the eshop09/23/2014 - 3:54pm
james_fudgere: MP, i've sent tech support a note - thank you :)09/23/2014 - 3:14pm
IanCNah that wasnt directed at you Andrew :)09/23/2014 - 3:00pm

MaskedPixelanteDear GP, something called "doubleverify" is causing some nasty browser issues on my end. Probably one of your ads.09/23/2014 - 2:36pm
Andrew EisenOh hell no. No, it took Nintendo a dog's age just to get to the point its competitors have been at for a while! (And it's still not there yet, in a lot of respects.)09/23/2014 - 2:26pm
IanCSame as PSN handles it, fi you are trying to say only nintendo do that.09/23/2014 - 2:23pm
Andrew EisenYou have to try to purchase something first. Pick a game, hit purchase and if your wallet doesn't have enough to cover it, you'll be given an option to "add exact funds" or something like that.09/23/2014 - 2:05pm
MonteI have seen no option for that on my 3DS; anytime i want to add funds it only gives me the option to add in denominations of $10, 20, 50 or 10009/23/2014 - 2:03pm
IanCWhat Andrew Wilson said. PSN is the same when you make a purchase over a certain price (£5 in the UK)09/23/2014 - 2:02pm
Andrew EisenNeither eShop charges sales tax either. At least in California.09/23/2014 - 2:00pm
Andrew EisenBoth Wii U and 3DS eShops allow you to add funds in the exact amount of whatever's in your shopping cart. If your game is $39.99, you can add exactly $39.99.09/23/2014 - 1:57pm
Infophile@Matthew Wilson: As I understand it, any regulations to force tax online would also set up an easy database for these stores to use, minimizing overhead.09/23/2014 - 1:30pm
MonteReally, the eshop just does next to nothing to make buying digitally advantagous for the customer. Its nice to have the game on my 3DS, but i can get more for less buying a physical copy at retail. And that's not even counting buying used09/23/2014 - 1:18pm
MonteIanC, The Eshop wallet system only lets you add funds in set denominations and the tax makes sure you no longer have round numbers so you ALWAYS loose money. A $39.99 game for instance requires you to add $50 instead of just $4009/23/2014 - 1:13pm
Matthew Wilsonbut thats just it those sites, even the small ones, sell all over the country.09/23/2014 - 11:12am
