What determines the quality of a digital radiography image?

The quality of a digital radiography image is primarily determined by the number of pixels and their size in the image. In digital imaging, pixels are the smallest elements of an image, and their arrangement forms the overall picture that is seen. A higher number of pixels generally leads to greater detail and clarity within the image, which is essential for accurate diagnostics. Additionally, pixel size influences the spatial resolution; smaller pixels can capture finer details, thus enhancing the image quality.

While resolution and contrast settings, type of radiation, and processing speed are important aspects of the imaging process, they do not directly dictate the intrinsic quality of the image itself. Instead, they contribute to how the image is captured, displayed, and interpreted but rely fundamentally on the pixel structure to maintain high-quality imaging.
