The original Star Trek aired from 1966 to 1969, and while its future looks a little dated today, its health care was ahead of its time. "Bones" McCoy was quick to tell Capt. James T. Kirk that he was "just a country doctor," but he still used high-speed imaging to diagnose the intergalactic maladies that landed those poor crewmen in sick bay at a time when, here on earth, X-rays were only used to tell you that a bone was broken. Now we diagnose our patients with ultrasound, CAT scans, PET scans and MRIs. They may not be handheld devices like Dr. McCoy's tricorder, but I read online that was just a painted salt shaker.
