<Tr> <Th> MeSH </Th> <Td> D005471 </Td> </Tr> <Tr> <Td_colspan="2"> (edit on Wikidata) </Td> </Tr> <P> Fluoroscopy (/ flʊəˈrɒskəpi /) is an imaging technique that uses X-rays to obtain real - time moving images of the interior of an object . In its primary application of medical imaging, a fluoroscope (/ ˈflʊərəˌskoʊp /) allows a physician to see the internal structure and function of a patient, so that the pumping action of the heart or the motion of swallowing, for example, can be watched . This is useful for both diagnosis and therapy and occurs in general radiology, interventional radiology, and image - guided surgery . In its simplest form, a fluoroscope consists of an X-ray source and a fluorescent screen, between which a patient is placed . However, since the 1950s most fluoroscopes have included X-ray image intensifiers and cameras as well, to improve the image's visibility and make it available on a remote display screen . For many decades fluoroscopy tended to produce live pictures that were not recorded, but since the 1960s, as technology improved, recording and playback became the norm . </P> <P> Fluoroscopy is similar to radiography and X-ray computed tomography (X-ray CT) in that it generates images using X-rays . The original difference was that radiography fixed still images on film whereas fluoroscopy provided live moving pictures that were not stored . However, today radiography, CT, and fluoroscopy are all digital imaging modes with image analysis software and data storage and retrieval . </P>
