Virtual Hearts and GPU Minds

August 19, 2011 -

Researchers at the Victor Chang Cardiac Research Institute in Sydney, Australia, are building a virtual heart to study the fatal effects that electrical disturbances can have on patients. This virtual heart, a real-time computer simulator, will allow medical researchers to study how structural changes to the body's most vital organ can interfere with its beating.

Eventually, the team hopes to develop personalized virtual hearts, allowing doctors to use a computer model of an individual's own heart to test treatments - before conducting the procedure on their patients in the real world. The leader of the project, cardiovascular researcher Adam Hill, said one of the main goals of the simulator is to provide a way for doctors to predict which patients may experience an electrical disturbance to their heart, or arrhythmia.

"If we can pick out patterns from simulations and try and understand why and when they occur, that could lead to much better prediction of who it is going to happen to," Dr Hill said.

For a simulator to be useful it must work as close to real-time as possible, so researchers had to come up with an effective way to compute billions of equations every few microseconds. While computer models of the heart have been built in the past, most have proven to be slow and ineffective, and not able to compute information fast enough. To overcome this problem, researchers turned to the technology used in graphics processing units - the same technology used to process the cutting edge 3-D graphics found in video games. The ability to link these processors together was also a boon to researchers.

Researchers also used a magnetic resonance image (MRI) of the heart to map its basic structure and geography onto a computer.

"From MRI you get details of scar regions, so we can map those onto our simulations and see how electrical patterns and structural alterations interact to cause an arrhythmia," he said.

Eventually, the team hopes to create personal virtual hearts based on a patient's own MRI scan to better diagnose and treat their conditions. Jamie Vandenberg, the deputy director of the institute, pointed out that being able to predict who may experience an arrhythmia, which causes about 15 percent of all deaths annually, would be a significant advance in medicine.

MechaTama31Haven't been to GOG in a while. Their website reminds me of the old Zune software now...08/27/2014 - 6:01pm
Andrew EisenAlso, I know it's nitpicking but only ONE of the 21 movies on offer goes for $15. Four more are $10 and the rest are $6. But right now, all of them are $6 (except for two that are free).08/27/2014 - 3:22pm
E. Zachary KnightMasked, What are you talking about? I guess you never buy DVDs either?08/27/2014 - 3:21pm
Andrew EisenNot if they've hired more people.08/27/2014 - 3:13pm
MaskedPixelantePlus, now that they're negotiating movies, that's LESS manpower to negotiate true, pre-2000, non-console-port classics.08/27/2014 - 3:08pm
MaskedPixelanteNo rewatch value, once you've seen it there's no reason to rewatch it, and it's 15 bucks down the drain.08/27/2014 - 3:06pm
E. Zachary KnightIndie movies are a great start. They need a great distribution system too.08/27/2014 - 3:04pm
Andrew EisenEven if that were true, so what?08/27/2014 - 3:01pm
MaskedPixelanteYou do realize that there are going to be NO Hollywood movies on this service, right? It's all going to be indie documentaries and stuff like that.08/27/2014 - 2:56pm
Andrew EisenI think it's an awesome next step for GOG and completely fail to see why anyone finds it problematic or improper.08/27/2014 - 2:51pm

Andrew EisenFalcon SNUB!!!08/27/2014 - 11:28am
E. Zachary KnightAh. Didn't realize Captain Falcon was from F-Zero. Perhaps they didn't want too much SSB cross over characters.08/27/2014 - 10:30am
ZenEZK they could easily just put Captain Falcon in (they are using his car anyways) and he would be the most recognizable character from the series for the anime, games, and Smash Bros.08/27/2014 - 9:42am
ZenMasked there are also the two from Animal Crossing that are going to be in it. I am wondering what they will do for the Excitebike level they gave a peek at.08/27/2014 - 9:41am
E. Zachary KnightDoes F-Zero really have a character that is recognizable that could be used? I would think the cars and tracks would be more recognizable.08/27/2014 - 8:55am
MaskedPixelantehttp://www.joystiq.com/2014/08/27/rockstar-lohans-gta-5-lawsuit-just-jonas-ing-for-publicity/ Rockstar releases the biggest "no duh" statement in the universe.08/27/2014 - 8:07am
MaskedPixelanteI'm just saying, they're giving us an F-Zero kart and an F-Zero track, but their crossover representative is Link?08/27/2014 - 8:00am
ZenMasked, not really sure what your are talking about lol. They will be giving a total of 6 characters, 8 vehicles, and 16 tracks...plus the Yoshi and Shy Guy sets if you get both packs. Not bad for about the price of a single CoD map pack lol.08/27/2014 - 7:02am
MaskedPixelanteSee the flaw here. Blue Falcon car, F-Zero themed track, and Link as a playable character.08/27/2014 - 6:46am
