Increasing the matrix size from 1024 x 1024 primarily affects which image attribute?

• A. Brightness levels
• B. Spatial resolution
• C. Exposure latitude
• D. Noise

Answer: (B)

Increasing the matrix size raises sampling density—more pixels across and down the image. If the field of view stays the same, the pixels become smaller, so the image can represent finer details. That finer sampling directly improves spatial resolution, which is the ability to distinguish small structures. Brightness is determined mainly by exposure and detector response, not by how many pixels are in the matrix, and exposure latitude and noise relate to dynamic range and photon statistics rather than pixel count in the matrix. So the primary attribute affected is spatial resolution.
