Question

Quizplus · Accepted Answer

Shuttering is a control on the viewing station that allows the blackening of the clear or white areas around the collimation edges of a radiograph. This helps to focus the viewer's attention on the diagnostic area of the image and reduce distractions from non-diagnostic information. Image stitching is a technique used to combine multiple images into a single image, and is not relevant to this question. Window width and window level are controls used to adjust the contrast and brightness of an image, and do not directly affect the blackening of the collimation edges.
