In this work, we introduce a novel self-gating method for radially acquired data based on a dimensionality reduction technique for time-series analysis (SSA-FARY).  ...  SSA-FARY reliably detects the cardiac and respiratory motion and separates it from noise.  ...  Here, we adapt the Singular Spectrum Analysis For Advanced Reduction of dimensionalitY, which we dub SSA-FARY [38, 39] .  ...

The respiratory motion signal is estimated from the filtered k-space center using an adapted singular spectrum analysis (SSA-FARY) technique.  ...  Aside from showing that a reliable respiratory motion signal can be estimated using modified SSA-FARY, in vivo studies with five healthy subjects demonstrate that high-resolution dynamic myocardial T1  ...  Estimating m 2 (t): Perform the singular spectrum analysis (SSA) on X(t), remove the components that are mostly related to the inversionrecovery contrast in the spectrum domain and transfer the processed  ...
