“…To generate the FSD graph, the normalized 1D FFTs of the profiles are plotted as a function of star pattern frequency (lp mm −1 ). The FSD is explicitly designed to quantify the harmonics, spectral leakage, and aliasing present in DBT planes, factors to which the MTF method is insensitive (Vent et al 2021).…”

“…We have created virtual versions of many physical test objects and simulated NGT acquisitions to create 3D reconstructions of the virtual phantoms. The simulations showed high concordance with the physical image reconstructions 15,28,33 …”

“…The spatial frequencies range from 1.27 line pairs‐per‐millimeter (lp/mm) to 16 lp/mm. The reconstructed images of the star patterns were analyzed in terms of the limit of spatial resolution (LSR), contrast transfer functions (CTFs), and Fourier spectral distortion (FSD) metric 28 . The CTF is extracted from the spine of the FSD graph, corresponding to a normalized frequency response of 1.0 cycle per line‐pair.…”
