The next time you have to get an MRI or CT scan you might not know it but if the equipment is made by GE it is phoning home.
No, the actual scan data is still between you and your doctor, but the broad stats of when and where the scan was taken is reported back to GE. In the true spirit of the Internet of Things, everything has an IP address, even an MRI machine. The analysts at GE have created some interesting data visualizations. About 125,000 scans are taken each day around the world with their equipment, and you can see time series information and other interesting stats on their blog.
