In digital mammography, increasing the number of pixels primarily affects which aspect?

Increasing the number of pixels mainly boosts spatial sampling across the image. A finer sampling grid means the detector records smaller variations in tissue density and sharper edges, so details that were previously blurred become more distinguishable. This directly improves spatial resolution—the ability to resolve small structures like microcalcifications. Keep in mind that the ultimate resolution is still limited by other factors such as the focal spot size and the detector’s blur (the system’s point spread function). Brightness is governed by exposure and detector response, while dynamic range depends on bit depth and camera electronics, and noise comes from photon statistics and electronics rather than how many pixels are in the array.
