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?  ;)

Michael ChandraWonderkarp, try games where you don't get interactive cutscenes and only the main character really talks to people. Or games with a silent protagonist. I think the Bechdel test is a nice indicator (though flawed) for movies and such, but not games.11/22/2014 - 7:56am
ZippyDSMleeWymorence: HTD was a fun and very messed up film I love it. A new one would be nothing like it sadly.11/22/2014 - 1:57am
Andrew EisenOnly if we lived in a world where a bad movie meant every subsequent attempt would suck. Seriously though, after the last few years, I'll give Marvel the benefit of the doubt that it could make a great Howard the Duck movie.11/22/2014 - 1:29am
Wymorenceisn't that a GOOD thing there isn't a movie after the abomination that was the first?11/22/2014 - 12:27am
Andrew EisenNo movie in sight but Howard the Duck is returning to comics! https://games.yahoo.com/news/howard-duck-series-announced-184400635.html11/21/2014 - 10:48pm
MechaCrashThe point of the Bechdel Test isn't "is this film sexist," it's to illustrate "this is an incredibly low bar and most movies STILL can't pass it."11/21/2014 - 10:11pm

Andrew EisenIf you missed the HuffPost segment I guested on, the replay is now embedded in the story.11/21/2014 - 6:05pm
Wonderkarphttps://pbs.twimg.com/media/B2__4yZCcAA9Ytp.jpg these look amazing. Peach is the only one I'm tempted to open cause her packaging is bent. get another nonbent one....man. toycollector me and gamecollector me is fighting11/21/2014 - 5:51pm
WonderkarpJust finalized my Smash Bros free Sound Track Order. Also got 4 amiibos and they look fantastic. I'm afraid to open them. they look spectacular!11/21/2014 - 5:45pm
james_fudgeCan we all agree that Andrew cleans up nicely and can go on any program?11/21/2014 - 5:01pm
Wonderkarpthank you for that line, Andrew. alot of great films fail the bechdel test. Gravity fails it and it has a female lead.11/21/2014 - 4:48pm
Andrew EisenAw, thanks James! Well, now I have to drive back to work!11/21/2014 - 4:45pm
Andrew EisenDidn't have a chance to say this on the HuffPost segment but while the Bechdel test is useful as a broad examination of gender representation in media, it's not at all appropriate as a judgment of quality.11/21/2014 - 4:45pm
james_fudgeAndrew you killed it!11/21/2014 - 4:44pm
WonderkarpMadeline Bergman. second female, they never speak of men, just a computer program. it passes the test11/21/2014 - 4:34pm
E. Zachary KnightDoes Other M have more than one woman in it?11/21/2014 - 4:31pm
Wonderkarpyet Metroid Other M, a game where people cried sexist due to the commanding officers restricting Samus, passes the test....11/21/2014 - 4:21pm
Wonderkarpwait...they are using the bechdel test to determine which games are sexist?.....how does that work with a game like Super Mario Bros when there is no Dialogue? test itself is BS. Alien doesn't pass it11/21/2014 - 4:20pm
