The lower the line pairs per millimeter, the better the spatial resolution
Indicate whether the statement is true or false
False. A line pair refers to the greatest number of paired lines visible in 1 millimeter (mm) of an image. For example, a resolution of 10 line pairs/mm would mean that when 10 ruled lines are squeezed into 1 mm of an image, the individual lines can still be distinguished from each other. The greater the spatial resolution in an image, the sharper it looks.
