I remember watching Star Trek, TOS, and Dr. McCoy would grab his tricorder and pull out a little gadget wave it around and then diagnose the patient based on the information displayed on the small tricorder screen. Years later it would be Dr. Crusher or the EMH with an updated version of the prop. Today...well it could be you. Scanadu has been working on a simple to use medical scanning device that is compatible with your smartphone.
The device is the result of one father having to spend almost a year inthe hospital with his sick child. He wanted to create a company and a device that would put that kind of information at your finger tips, that would allow you to store the information to share with your Doctor to help with diagnosis.
