Yesterday, the Food and Drug Administration announced a new initiative to increase the safety of imaging devices that use radiation, like CT scans. This came about because of a New York Times investigation detailing horrifying cases of patients being given overdoses of radiation when going in for routine scans. Hospitals are employing incredibly powerful equipment that can -- and has -- killed people if used incorrectly. The machinery sometimes lacks systems that would prevent these deaths, like an alarm telling the technician when they're about to deliver an overdose of radiation.
