What negative effect does scatter have on image quality?

Scatter in imaging systems, such as those involving image intensifiers, leads to a reduction in contrast, creating what is referred to as contrast-reducing haze. When scatter occurs, it results from x-rays interacting with different materials in the body or imaging environment, causing some of them to deviate from their original path. This scattering dilutes the signal of the desired image by adding unwanted information that obscures the details, resulting in a hazy appearance. The overall quality of the image is compromised because the essential contrast needed to differentiate between various tissues or structures diminishes. In contrast, the other options suggest improvements or no adverse effects on image quality, which does not accurately reflect the impact of scatter. Thus, the correct choice directly relates to the negative implications scatter has on image clarity and detail.
