In Denmark, about 350 babies need to be operated each year because of heart defect. And their hearts are very small, so it's hard to know the exact kind of defect before the operation. This is why the Aarhus University Hospital is using virtual reality software to model babies' hearts, according to BBC News. Now, surgeons and doctors can visualize a magnified heart in 3D before planning cardiac surgery. This also allows a better communication with parents which can understand what's wrong with their babies before the intervention. As the percentage of affected babies, about one per cent, is probably the same in many other countries, let's hope this software will be widely distributed. Congratulations to these Danish doctors and software writers for this brilliant usage of technology.Here are how the system works.
The system turns flat images produced by conventional MRI body scanners into giant, rounded models of the child's heart, which surgeons can navigate through and explore from every angle. [And] the virtual reality (VR) system takes some of the guesswork out of the diagnosis.
Let's listen to one of the early testers, Paediatric Surgeon Ole Kromann Hansen.
He told the BBC's Go Digital programme that because many people could view the child's virtual reality heart at once, all members of the medical team could discuss and agree on the diagnosis knowing they were all viewing the organ from the same angle.
And for the parents of affected children, this system is an important advance. "It's difficult to explain to parents what kind of heart defect their child has," he said.

The software has been developed by Systematic Software Engineering in collaboration with the Center for Advanced Visualization and Interaction (CAVI) in Aarhus.

For more technical information, the research work has been published by Circulation last June. Here is a link to the abstract of the paper named "Operator-Independent Isotropic Three-Dimensional Magnetic Resonance Imaging for Morphology in Congenital Heart Disease: A Validation Study.".

Famous quotes containing the words virtual, reality, helps, treat and/or hearts:
“Neither dead nor alive, the hostage is suspended by an incalculable outcome. It is not his destiny that awaits for him, nor his own death, but anonymous chance, which can only seem to him something absolutely arbitrary.... He is in a state of radical emergency, of virtual extermination.”
—Jean Baudrillard (b. 1929)
“The glorious dream of full father involvement in infant care will not become a widespread reality overnight. But it can happen, and it eventually will happen,... A lot of progress may take place in a short period of time if we just lighten up, step back, and give the guys a decent chance.”
—Michael K. Meyerhoff (20th century)
“You cant be a Real Country unless you have A BEER and an airlineit helps if you have some kind of a football team, or some nuclear weapons, but at the very least you need a BEER.”
—Frank Zappa (19401993)
“Friendship is learned by watching and listening to you. If she sees that your friends are people you like and trust and dont pretend withpeople who suit youshe probably wont pick friends who just pass by, or people who can help her or improve her status. If you treat friends in a special way, if you are kinder, more generous, more sympathetic, more forgiving with friends, she probably will be, too.”
—Stella Chess (20th century)
“So long as the law considers all these human beings, with beating hearts and living affections, only as so many things belonging to the masterso long as the failure, or misfortune, or imprudence, or death of the kindest owner, may cause them any day to exchange a life of kind protection and indulgence for one of hopeless misery and toilso long it is impossible to make anything beautiful or desirable in the best-regulated administration of slavery.”
—Harriet Beecher Stowe (18111896)
