Paper Abstract

The major potential errors in the slit method measurement of the line spread function (LSF) and the modu-lation transfer function (MTF) of radiographic screen-film systems are reviewed. These errors are compared with the potential error introduced in the LSF due to an erroneous representation of the characteristic curve (sensitometric data). If a deviation in the sensitometric data results in a lower average gradient of the characteristic curve, the MTF will show higher resolution capabilities.
