Benchmarking of single imaging datasets

A method of estimating a value (311-313) indicative of a signal component of an input imaging dataset (190) includes determining a normalized Fourier-domain representation of the input imaging dataset (190); and for each one of multiple low-pass filters (320) having varying cut-off frequencies (301, 301-1, 301-2): determining the respective low-pass filtered normalized Fourier-domain representation of the input imaging dataset (190) based on the normalized Fourier-domain representation of the input imaging dataset and performing a respective comparison of the respective low-pass filtered normalized Fourier-domain representation of the input imaging dataset with the input imaging dataset; and based on results (302, 303) of the comparisons associated with the low-pass filters: estimating the value (311-313) indicative of the signal component of the input imaging dataset (190).
