Ch 33 Fluoroscopy
(solved& updated)
Fluoroscopy Overview - answer Used for dynamic function studies in
which diagnosis takes place during the exam
Primarily the domain of the radiologist
Early fluoroscopy timeline - answer 1896 first discovery
1907 practice emerged
1929 Wappler Fixed Room Fluoroscopy
1948 image intensifier tube invented
First fluoroscopes were handheld, dark room, primary beam directed at
radiologist's viewing hood
Radiographer guidelines - answer Assistant during fluoroscopic exams
, Post-fluoro images
Some states require distinct licensure
