What does spatial resolution refer to in imaging?

Spatial resolution refers to the ability of an imaging system to distinguish between small structures that are close together in the image. It directly correlates with the sharpness and detail of the structures recorded within the image. Higher spatial resolution results in clearer images where finer details can be identified and analyzed, making it crucial for accurate diagnosis and assessment in medical imaging.

For instance, in radiography, improved spatial resolution allows for better visualization of small lesions or anatomical details, enabling medical professionals to make informed decisions based on the images. This aspect of imaging quality emphasizes the importance of resolution in creating precise and helpful representations of the internal structures of the body.
