Wired - The Doctor Will See Your Prototype Now:
"To Peter Hunter, the future of medicine looks like this: You visit your doctor after weeks of feeling fatigued and lethargic. She takes a blood sample, records your DNA profile, does a quick CT body scan, then uploads the raw data to a workstation. Within minutes, software stitches together a head-to-toe living, breathing digital reproduction of your innards, which the doc can poke and prod just like the real thing. Turns out you have lung cancer. Rather than focusing on one treatment, your physician can test various scenarios on your digital doppelgänger - surgery, radiation, chemotherapy - and watch how your system reacts. The cure is the simulation that doesn't kill the virtual you."
