Published	05/01/2023	Imaging Physics: Fluoroscopy PhysicsCompared to a standard chest X-ray exposure of 5 μGy, each fluoro frame has {{c1::500}}x fewer incident photons.
Published	05/01/2023	Imaging Physics: Fluoroscopy PhysicsFor fluoroscopy, there is a federal regulatory limit of {{c2::100}} mGy/min entrance air kerma.
Published	05/01/2023	Imaging Physics: Fluoroscopy PhysicsFor fluoroscopy, federal regulations will allow high-dose fluoro with audible/visual alarms at {{c1::200}} mG…
