Digital Fluoroscopy Questions and Answers, Graded A+ Digital Fluoroscopy identifies a digital x-ray imaging system that produces a series of dynamic images obtained with an area x-ray beam and an image intensifier or flat panel device. The difference between conventional fluoroscopy and Digital Fluoroscopy is the nature of the image and the manner in which it is digitized. The advantages of DF over conventional fluoro are: 1. the speed of image acquisition 2. post-processing t...

Chapter 36: Fluoroscopy Questions and Answers, Graded A+ Fluoroscopy a dynamic radiographic examination; involves active diagnosis during an examination Image Intensification Tube video camera and monitor used to view fluoroscopic images Thomas Edison invented a more notable fluoroscope in 1896 His fluoroscope produced a very faint image that one viewed while standing in the path of the x-ray beam as it exited the patient and screen. It had two drawbacks: The dose to the ...
