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 EisenI made this video about two years ago but it's topical again. "The Effects of Gay Marriage" https://www.youtube.com/watch?v=lcFyxiYu9I406/30/2015 - 12:12pm
black mantaA little more compact, but still not a radical re-design.06/30/2015 - 12:00pm
SuperKeegYeah, the proton pack is different in design, but similar in spirit. Its a little dirty, not pretty, but functional.06/30/2015 - 11:08am
IvresseI'm guessing it's specifically designed to be smaller. The original packs were pretty bulky looking...06/30/2015 - 11:07am
E. Zachary KnightThe proton pack is a very different design. Here is the original: http://www.gbfans.com/wiki/Proton_Pack_Part_Names06/30/2015 - 10:50am
black mantaProton pack looks essentially the same to me. Have no problem with either, BTW. :)06/30/2015 - 10:32am
Andrew EisenNot much change to the uniforms so I was surprised to see such a redesign for the proton pack. I like it though!06/30/2015 - 10:22am

Mattsworknamegamergate or any part of that movment. My biggest issues have always been more about my views on the idustry on a personal level rather then any affilication with GG.06/30/2015 - 9:50am
MattsworknameI only really every had any interest in the GG stuff when they were going in about the media and stuff and the whole "Gamers are Dead" junk. As a general rule, whatever issues I had with various groups was more my own issues, not anything specific with06/30/2015 - 9:49am
Andrew EisenI'm still trying to figure out where anyone is getting the idea violent content or lousy representation of women and minorities in video games shouldn't exist or be promoted.06/30/2015 - 9:25am
james_fudgeWell, members of GP first, members of GG second, I always say.06/30/2015 - 9:06am
black mantaConsidering it's only you and Mattsworkname that have been carrying the banner for it here, that pretty much testifies to how little influence they have. Most everyone else here couldn't care less.06/30/2015 - 8:54am
black mantaAgain GG is more like Occupy Wall Street than the Tea Party movement. They had their moment, but they fizzled out. And now exist more as a nebulous thing spouting ideas. They haven't achieved anything meaningful.06/30/2015 - 8:52am
black mantaAs sincere as your beliefs may be, the movement is still rife with bigots and misogynists.06/30/2015 - 8:51am
black mantaI'm sure you're heart's in the right place, Goth. But it doesn't excuse the behavior of GG's members towards the people they don't like.06/30/2015 - 8:50am
MattsworknameWow goth, write a novel why dont cha. Seriously I know you have a passion for this stuff, but wow, thats kinda overkill.06/30/2015 - 8:46am
james_fudgeI hereby dub this space the Mainifesto Box (tm)06/30/2015 - 8:34am
Infophile13 shouts in total by Goth in a row. I think I'm to blame here. If I'd read the Breitbart link when he'd posted it, maybe he wouldn't have felt the need to say everything here.06/30/2015 - 8:27am
