Remember the film Innerspace [http://www.imdb.com/video/screenplay/vi4136698137/] where back in 1987 Dennis Quaid’s scientist character is miniaturised and travels inside the body of an unsuspecting store clerk played by Martin Short? It all seemed very futuristic at the time.
Well, at the University of New South Wales in Sydney, Australia, they are working on making that a reality – almost! Using Virtual Reality they are able to explore the inner workings of a cancer cell, and have plans to create 3D virtual representations, using MRI and CT scan information, of the arteries of people who have had strokes, with the idea that if you could walk, virtually, through your own arteries and see what is happening to them this may help with rehabilitation, by encouraging you to make good choices and ultimately speed long term recovery.
Besides it looking incredibly cool and alien, it is also hoped that this technology will help create new disease-busting drugs, as well as helping people understand their own body on a nano level!
