Physical by smartphone becoming real possibility

WASHINGTON (AP) — It's not a "Star Trek" tricorder, but by hooking a variety of gadgets onto a smartphone you could almost get a complete physical — without the paper gown or even a visit to the doctor's office. Blood pressure? Just plug the arm cuff into the phone for a quick reading. Heart OK? Put your fingers in the right spot, and the squiggly rhythm of an EKG appears on the phone's screen. Plug in a few more devices and you could have photos of your eardrum (Look, no infection!) and the back of your eye, listen to your heartbeat, chart your lung function, even get a sonogram.
