Question: 1 / 1100

What aspect of the image is affected by adjusting the window level?

Contrast

Brightness

Adjusting the window level primarily affects the brightness of the image. In digital radiography, the window level represents the center of the range of pixel values that will be displayed. When the window level is changed, the balance of brightness across the image is altered, which can either brighten or darken the overall image, depending on whether the level is increased or decreased.

While brightness change is evident upon adjusting the window level, other factors such as contrast can still be impacted indirectly; it is essential to note that the actual contrast of the image is more directly related to window width adjustments. Sharpness and clarity are more associated with factors like resolution and noise rather than adjustments made to window settings. Thus, understanding the window level's role emphasizes how brightness is manipulated to enhance image interpretation in radiographic practice.
