Image Intensifiers - Video Lesson

Hey, everybody. Welcome in this lesson. We are discussing the image intensifier its purpose and fluoroscopy, its components, and how those components work together. The image intensifier is an important component of the imaging chain because it brightens the fluoroscopic image so that it can be of diagnostic value. In fluoroscopy, either a continuous or pulsed x-ray beam is used create dynamic real time images of internal structures. Because of this increased exposure time, a lower MA is used to reduce patient dose, and because of this lower quantity X-ray beam, the initial fluoroscopic image is dimmer than those in static X rays. The image intensifier helps to brighten the by amplifying the lower quantity X-ray beam. What are the components of an image intensifier? The components of an image intensifier are an input phosphor, A photocathode, electrostatic focusing lenses, an anode,
