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.

MechaCrashHey Neo, that bit with "he instigated it"? That is called victim blaming. Stop it.10/25/2014 - 11:05pm
KronoAnd a rebuttal to that article: https://medium.com/@cainejw/an-actual-statistical-analysis-of-gamergate-dfd809858f6810/25/2014 - 9:42pm
Technogeekhttp://www.newsweek.com/gamergate-about-media-ethics-or-harassing-women-harassment-data-show-27973610/25/2014 - 8:54pm
TechnogeekAnd speaking of harassment and Gamergate, Newsweek had a social media analytics company analyze the hashtag in the interest of finding out what the movement was really about. The results should surprise absolutely nobody at this point.10/25/2014 - 8:54pm
Neo_DrKefkaI was called a traitor for speaking out on harassment and I was put on a list for people on twitter to mass report me. Only GamerGate site that has come out of this that has been reputable would be TechRaptor. 2/210/25/2014 - 7:09pm
Neo_DrKefka@Neeneko The reason why I ended my support of #GamerGate was the fact KingofPol (The guy who was sent the knife) ended up saying crap about those with autism. At this point I confronted the community and some big wig writers on the #GamerGate side. 1/210/25/2014 - 7:08pm
NeenekoIt would also mean they have to confront that the sites already mostly cater to them and wiping that small percentage of otherness just does not justify new sites.10/25/2014 - 6:55pm
Neeneko@ quiknkold - problem is it has never been about freedom, it is about dominance, ownership, and priviliage. women and minorities should be the ones leaving and creating their own spaces, not them!10/25/2014 - 6:54pm
Neo_DrKefka@Mecha I hear you about KingofPol this is a guy who is using GamerGate to boost his career. Most of his streams are crap about him talking about him being drunk. What happened to him was wrong but it doesn't change the fact he has instigated much of this10/25/2014 - 5:40pm
Craig R.And I'll be perfectly happy in never seeing the phrase 'false flag' ever again, as it is one of the worst notions to ever come out of the camp of the tinfoil brigade that is already completely overused.10/25/2014 - 3:50pm
Craig R.Gone for a week and come back to find GG didn't go away at all. Dammit.10/25/2014 - 3:48pm
Matthew Wilsonif they were serious, they would go to youtube. most youtube game reviewers tend to revew games as product, and tend leave social issues out of it.10/25/2014 - 1:42pm
quiknkoldif the gamergaters were serious, they'd realize that Kotaku and Polygon arent the only games in town, and that with the freedom of the internet, they could create their own websites and achieve the goals they are trying to achieve without arguement.10/25/2014 - 1:35pm
james_fudgehe should have called the police.10/25/2014 - 1:20pm
TechnogeekAt least my statement still holds if it does turn out to be a false flag.10/25/2014 - 1:03pm
NeenekoThough I admit, since doxxing and false flag where heavily used tactics of the GG supporters, while they are not historical tactics used by detractors, I am skeptical how much it is really 'both sides' doing it in any real volume.10/25/2014 - 1:01pm
NeenekoOne thing that makes all of this messy is 'false flag' is a serious concern here. It does not help that the original GG instigators were also known for doing elaborate false flags to discredit feminism themselves.10/25/2014 - 12:59pm
MechaCrashThe guy who got the knife is the one who advocated doxxing, by the way, and was getting court documents about Zoe Quinn so he could publicly post them. It doesn't make what happened to him right, but he deserves no sympathy.10/25/2014 - 12:42pm
TechnogeekNo, that's a pretty shitty thing to do and I fully support the responsible parties getting a visit from the relevant legal authorities.10/25/2014 - 12:17pm
Neo_DrKefkaSomeone anyone tell me how two wrongs somehow make a right? This is becoming exhausting and both sides are out of there minds!10/25/2014 - 11:40am
