What term describes the amount of detail or sharpness in a digital image?

Spatial resolution refers to the amount of detail or sharpness in a digital image. It is a critical factor in imaging because it determines how well small structures can be distinguished from one another. In the context of X-ray imaging, higher spatial resolution means finer detail, allowing radiologists and medical professionals to detect and diagnose conditions more accurately.

Spatial resolution is influenced by various factors, including the pixel size of the detector, the technique used, and the specific imaging equipment. A high spatial resolution ensures that the images produced are clear and provide the necessary detail for effective analysis. This capability is especially important in medical imaging where precision is paramount for diagnosis and treatment planning.

Contrast resolution, on the other hand, refers to the ability to differentiate between varying shades of gray in an image, while temporal resolution pertains to the ability to capture changes over time, which is particularly relevant in dynamic imaging. Image quality is a broader term that can encompass several factors, including spatial resolution, contrast resolution, and other aspects of the imaging process, but spatial resolution specifically pinpoints the sharpness and detail of the image.
