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?  ;)

MaskedPixelanteNevermind. Turns out when they said "the patch is now live", they meant "it's still in beta".12/19/2014 - 5:07pm
MaskedPixelanteSo I bought Dark Souls PC, and it's forcing me to log into GFWL. Did I miss something?12/19/2014 - 5:00pm

E. Zachary KnightIf you are downloading a copy in order to bypass the DRM, then you are legally in the wrong. Ethically, if you bought the game, it doesn't matter where you download it in the future.12/19/2014 - 12:06pm
InfophileEZK: Certainly better that way, though not foolproof. Makes me think though: does it count as piracy if you download a game you already paid for, just not from the place you paid for it at? Ethically, I'd say no, but legally, probably yes.12/19/2014 - 11:20am
ZippyDSMleeAnd I still spent 200$ in the last month on steam/GOG stuff sales get me nearly every time ><12/19/2014 - 10:55am

ZippyDSMleeE. Zachary Knight: I buy what I can as long as I can get cracks for it...then again it I could have gotton Lords of the Fallen for 30 with DLC I would have ><12/19/2014 - 10:50am
MaskedPixelantehttp://www.joystiq.com/2014/12/19/marvel-vs-capcom-origins-leaving-online-storefronts-soon/ Speaking of "last chance to buy", Marvel vs. Capcom Origins is getting delisted from all major storefronts. Behold the wonders of the all digital future.12/19/2014 - 9:59am
MaskedPixelanteSeriously, the so-called "Last Chance" sale was up to 80% off, while this one time only return sale goes for a flat 85% off with a 90% off upgrade if you buy the whole catalogue.12/19/2014 - 9:37am
E. Zachary KnightInfophile, Tha is why I buy only DRM-free games.12/19/2014 - 9:37am
MaskedPixelanteNordic is back on GOG for one weekend only. And at 85% off no less, which is kind of a slap in the face to people who paid more during the "NORDIC IS LEAVING FOREVER BUY NOW OR FOREVER HOLD YOUR PEACE" sale, but whatever...12/19/2014 - 9:28am
InfophileRe PHX's link: This is one of the reasons the digital revolution isn't all it's cracked up to be. There's also the flip side where Sony can block access to games you've bought if they ban your account for unrelated reasons. All power is theirs.12/19/2014 - 8:52am

Papa MidnightAh, so it was downtime. I've been seeing post appear in my RSS feed, but I was unable to access GamePolitics today across several ISPs.12/18/2014 - 6:06pm
james_fudgeSorry for the downtime today, folks.12/18/2014 - 5:54pm
