1. increasing, width
2. decreasing, level
3. decreasing, width
4. increasing, level

Answer 1

To make the image appear darker to evaluate bony structures, one should decrease the window width, which increases the contrast, highlighting the bone details more clearly.

Step-by-step explanation:

The question is addressing the manipulation of radiological images to better visualize the bony structures. To make an image appear darker which would allow for better evaluation of bony structures, the correct action would be decreasing the width of the window. This refers to narrowing the range of Hounsfield units (grey values) displayed on the image, which increases the contrast and makes the bony structures more pronounced against the background.
