Fluoroscopic Image Quality - Video Lesson

The measures of optimum image quality and fluoroscopy are similar to those used in radiography, spatial and contrast resolution, as well as image distortion. Let's take a look at these common fluoroscopic image quality characteristics. Image intensifiers have been in fluoroscopy for decades, and with the constant improvements made to these energy conversion tubes, There are still imaging features that negatively impact image quality. Most of the weaknesses of image intensifiers center around the simple fact that it is a tube technology with curved surfaces coated with a scintillating phosphor to create and control the flow of electrons. Image quality weaknesses such as vignetting, pin cushioning and distortion occur due to
