The window width is primarily used to adjust:

• A. Brightness
• B. Gray scale (contrast)
• C. Area irradiated
• D. Imaging plate integrity

Answer: (B)

Window width controls the range of gray values displayed on the image. By narrowing that range, you map a smaller set of gray shades to the display, which increases contrast and makes differences between tissues more pronounced. Widening the range broadens the gray scale and reduces contrast. This parameter doesn’t change the brightness (that’s the window level), nor does it affect how much radiation was used or the physical condition of the imaging plate, so its primary role is to adjust the gray scale (contrast).
