In imaging, what does the term 'sharpness' refer to?

In imaging, the term 'sharpness' specifically refers to the clarity and detail of an image. It encompasses the degree to which fine details can be distinguished and perceived in the final output. Sharpness is influenced by several factors, including the resolution of the imaging system, the quality of the lenses used, the contrast present in the image, and the techniques applied during image acquisition and processing.

A sharper image reveals more detail, allowing for better diagnosis and interpretation in radiology, as healthcare professionals rely on the clarity of images to make informed decisions about patient care. Therefore, the aspect that defines sharpness is directly tied to the image's ability to represent fine structures distinctly rather than any other elements such as brightness, speed, or size.
