Final answer:
Increasing the Source-to-Image Distance (SID) in imaging systems can improve spatial resolution and image quality.
Step-by-step explanation:
Increased SID (Source-to-Image Distance) in imaging systems, such as X-ray machines, can improve spatial resolution.
This is because spatial resolution is determined by the size of the pixels or detector elements in the imaging system. When the SID is increased, the same number of pixels are spread over a larger area, resulting in a finer resolution and better image quality.
For example, in X-ray imaging, increasing the SID allows for better visualization of small structures, such as fractures, that may otherwise be difficult to detect.
