A medical imaging device that uses X-rays and a fluorescent screen to produce real-time moving images of internal body structures, allowing doctors to see bones and organs in action.
From fluoro- (fluorescence) + Greek skopein, 'to view'. Invented in the early 1900s as X-ray technology combined with fluorescent materials for live imaging.
The fluoroscope was medicine's first 'action camera'—it let doctors watch your heart beat, bones flex, and swallow move in real-time, but early machines exposed patients to dangerous radiation before safety limits were established.
