Contrast (Digital Factors) - Video Lesson

Hey, everybody. Welcome back. This lesson discusses the digital factors that influence image contrast and radiography. For the purpose of this video, digital factors includes those processes taking place within the computer system after the exposure has taken place. This includes computer processing, like histogram analysis, and the lookup table. Also post processing, this is called windowing, and the monitor display calibration. Called the grayscale standard display function. We'll talk about all of these factors in detail. So why do these digital factors matter? These are the factors that have the most important impact on image contrast more so than KDP, grids, subject contrast, or any other procedural factor. Here's an example. Let's say we're acquiring an abdominal radiograph on a very
