I was thinking today about diagnosing a patient and how it would be cool for doctors to wear some sort of Google Glasses type device linked to a computer. The headset could have a heads up display showing the vitals like heart rate, blood pressure, etc. Of course it would also monitor commands given by the doctor and show contraindications where appropriate. For instance a doctor might order a certain drug be administered and the computer would compare that against medications the patient was taking. Then if it found a problem it could vibrate and flash a warning on the screen.
Speaking of voice commands, the doctor could instantly call up symptoms of any disease and ask the computer to compare that to those of the patient. All the while watching the results or progress on his heads up display.
Such a system could also theoretically show a surgeon the appropriate place for an incision.
Even better the system might pull up images from previous surgeries the patient had to compare any changes.
Of course this would be a dream come true for a Dentist. The system automatically overlaying past images over real-time captures. Take that a step further and imagine the patient smiling into a camera at home and having the computer recommend adjustments to braces or signing off that things look good. Remember images coming from across town from a remote camera would appear live in the same headset thing.
Now take it a step further and the headset camera could help a surgeon map out an area of cancerous material, superimposing over it in varying colors to indicate boundaries.
