How does scatter radiation impact digital radiographic images?

Scatter radiation significantly impacts digital radiographic images by degrading image quality. When X-rays interact with matter, such as patient tissue, some of them scatter in different directions rather than passing straight through. This scattered radiation increases the overall exposure of the detector and can lead to a reduction in contrast, making it difficult to distinguish between different tissues or structures in the image.

In digital radiography, the detector is designed to capture the primary beam's information, which is vital for producing high-quality images. The presence of scatter radiation adds noise to the image, resulting in a loss of sharpness and clarity. Therefore, understanding how scatter affects image quality is crucial for improving diagnostic accuracy and optimizing image acquisition techniques.
