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.

Andrew EisenAs it happens, Chinatown Wars is the only GTA game I've played.04/19/2014 - 10:43am
Papa MidnightWith GTA5 (to date) failing to even provide indication of a PC release, I'm realising that this might be the first GTA game that I have not played (outside of Chinatown Wars) since the series inception.04/19/2014 - 8:14am
IanCSo im guessing a bunch of edutainment games, which a lot of people elsewhere are going gaga over, dot count as classics? Okay. If you don't mind me, i have a sudden urge to play Putt Putt....04/19/2014 - 6:15am

Matthew Wilsonit is a video talking about why certain games/products/consoles do well, and others do not. he back it up with solid research.04/18/2014 - 3:56pm
Andrew EisenI'm not keen on blind links. What is it?04/18/2014 - 3:45pm
Matthew Wilsonthis is worth a whatch https://www.youtube.com/watch?v=MyXcr6sDRtw&list=PL35FE5C4B157509C904/18/2014 - 3:43pm
MaskedPixelanteNumber 3: Night Dive was brought to the attention of the public by a massive game recovery, and yet most of their released catalogue consists of games that other people did the hard work of getting re-released.04/17/2014 - 8:46pm
MaskedPixelanteNumber 2: If Humongous Entertainment wanted their stuff on Steam, why didn't they talk to their parent company, which does have a number of games published on Steam?04/17/2014 - 8:45pm
MaskedPixelanteNumber 1: When Night Dive spent the better part of a year teasing the return of true classics, having their big content dump be edutainment is kind of a kick in the stomach.04/17/2014 - 8:44pm
Matthew Wilsonhttp://www.giantbomb.com/articles/jeff-gerstmann-heads-to-new-york-takes-questions/1100-4900/ He talks about the future games press and the games industry. It is worth your time even though it is a bit long, and stay for the QA. There are some good QA04/17/2014 - 5:28pm
IanCErm so they shouldn't sell edutainment at all? Why?04/17/2014 - 4:42pm
MaskedPixelanteNot that linkable, go onto Steam and there's stuff like Pajama Sam on the front-page, courtesy of Night Dive.04/17/2014 - 4:13pm
Andrew EisenOkay, again, please, please, PLEASE get in a habit of linking to whatever you're talking about.04/17/2014 - 4:05pm
MaskedPixelanteAnother round of Night Dive teasing and promising turns out to be stupid edutainment games. Thanks for wasting all our time, guys. See you never.04/17/2014 - 3:44pm
Matthew WilsonAgain the consequences were not only foreseeable, but very likely. anyone who understood supply demand curvs knew that was going to happen. SF has been a econ/trade hub for the last hundred years.04/17/2014 - 2:45pm
Andrew EisenMixedPixelante - Would you like to expand on that?04/17/2014 - 2:43pm
MaskedPixelanteWell, I am officially done with Night Dive Studios. Unless they can bring something worthwhile back, I'm never buying another game from them.04/17/2014 - 2:29pm
