tracking perfusion evaluation relies on the deconvolution of a tracer
concentration time-courses in an arterial and a tissue voxel following the
tracer kinetic model. The object of this work is to propose a method to
design a data driven Tikhonov regularization filter in the Fourier domain and
to compare it to the singular value decomposition (SVD) based approaches
using the mathematical equivalence of Fourier and circular SVD (oSVD).
