Modulation Transfer Function on edge
From AutoPIA
Modulation Transfer Function (MTF) values are calculated according to I.A. Cunningham and A. Fenster "A method for modulation transfer function determination from edge profiles with correction for finite-element differentiation" (Med Phys. 1987 Jul-Aug;14(4):533-37). Authors demonstrate how MTF can be calculated from the profile from an edge using the Edge Spread Function (ESF) and the Line Spread Function (LSP) applying a correction for taking into account that ESP and LSP are finite-element functions.
A graph visualizes the resulting MTF.
