Final answer:
Scatter radiation influences radiographic quality by decreasing the contrast.
Step-by-step explanation:
Scatter radiation influences radiographic quality by decreasing the contrast.
Scatter radiation occurs when X-rays interact with matter and are deflected in different directions. This scattered radiation can cause a loss of contrast in the radiographic image, making it difficult to distinguish between different structures or densities. The scattered X-rays reduce the difference in density between different parts of the image, resulting in a decrease in contrast.
For example, let's say you have an X-ray image of a chest. If there is a lot of scatter radiation present, the lungs and other soft tissues may appear less distinct, and it may be harder to see abnormalities such as tumors or fluid buildup.
