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.

MechaTama31That's a pretty difficult anatomy to break.02/26/2015 - 11:09pm
MechaTama31"the way her animations repeatedly break her anatomy" <-- I'm sorry, but we are talking here about the woman who can roll up into a little ball and live to tell the tale, yes? ;)02/26/2015 - 11:09pm
Andrew EisenAs far as examples that could be culled from female game characters though, that one's pretty mild.02/26/2015 - 9:11pm
Andrew EisenNot as much the heels or the suit in and of themselves but certainly the way her animations repeatedly break her anatomy to show off her lady bits.02/26/2015 - 9:10pm
E. Zachary KnightWell, Samus's heels are certainly impracticable, but I wouldn't really call her Zero suit objectified. I don't really feel that the new Lara Croft is objectified either, but that is my subjective opinion.02/26/2015 - 9:08pm
Andrew EisenTomb Raider: No but we haven't seen much of anything yet. Samus: Yes.02/26/2015 - 9:07pm
ZippyDSMleeWould you call the new tomb raider objectified? WOuld Samus Aran from the new Smash bros be objectified?02/26/2015 - 9:02pm
WonderkarpI'm hoping they put the rest of the comic book ghostbusters in there. Ortiz and Rookie(From GB the game)02/26/2015 - 8:38pm
Wonderkarpghostbusters board game is doing great. getting close too a 3rd extra playable Character. Ron Alexander.02/26/2015 - 8:37pm
Andrew EisenSmurfette is not subjective. If there's more than one female character, it's not Smurfette. Anyway, as with everything on the list, Smurfette is, in and of itself, not necessarily a bad thing.02/26/2015 - 8:32pm
Andrew EisenI think there's 5 women (out of 15, I think) but other than one being a bit more "hippy" than the others, they pretty much all have the same body type. Especially when compaired to the huge variety of male body types.02/26/2015 - 8:31pm
Wonderkarpso I dont see Smurfette as a bad thing. Unless like all your female characters are Smurfette. remember the Smurfs also had Sassette02/26/2015 - 8:29pm
E. Zachary KnightOne good example of the larger issues is one Anita used in the presentation, Blizzard's Overwatch game. There are a dozen men in the game with a dozen body types. But there are only 4 women with 2 body types, but 3 of them have the same one.02/26/2015 - 8:28pm
Wonderkarpthe smurfette thing is subjective to how many female characters you have. Take Sonic for example. You have Amy, who is obvious smurfette, but there's several other female characters now without that. Including the original animated seriescomics with Sally02/26/2015 - 8:28pm
E. Zachary KnightAE. Very true. I think that is where I was going, but it didn't come out right. Jack Harkness is sexy but not objectified. Whereas, a women would have to be objectified in order to be "sexy" in most games.02/26/2015 - 8:26pm
E. Zachary KnightAnd as Andrew pointed out, there is a big difference between a sexualized man, and an idealized man. But for some reason, there is no distinction between women in games. For the most part.02/26/2015 - 8:25pm
Andrew EisenI think one of the issues we run into repeatedly with these conversations is the confusion over "sexy" and "sexually objectified."02/26/2015 - 8:24pm
E. Zachary KnightYet, for some reason, in orde rto have a sexualized women, she must be wearing lingerie or a bikini. Can't women be sexual and still dress for the job at hand?02/26/2015 - 8:24pm
E. Zachary KnightThe problem I have with complaints of "sexualized men" is that men don't have to wear speedos to be sexualized. Captain Jack Harkness from Torchwood/Doctor Who, was one sexy man, but he spent 99% of his time in a WW2 soldier's trenchcoat.02/26/2015 - 8:23pm
Andrew EisenThat there's more to her character than her sexualization? Sure (depending on which depiction we're talking about). No one's claiming that there are zero examples of female characters beyond their sexualization.02/26/2015 - 8:22pm
