Modulation Transfer Function. In practice the mtf is measured with a square wave instead. The modulation transfer function mtf is defined as the modulation mi of the image divided by the modulation mo of the object.
On the radiogram objects having different sizes and opacity are displayed with different gray scale values. Mtf is used for components as simple as a spherical singlet lens to those as complex as a multi element telecentric imaging lens assembly. On the radiogram objects having different sizes and opacity are displayed with different gray scale values.

The modulation transfer function mtf is the spatial frequency response of an imaging system or a component. Carlson center for imaging science college of science rochester institute of technology. 18 rather than point objects. Lens aperture diffraction also limits mtf.
