From left to right shows the reference map (high-dose CTP), the low-dose maps of standard singular value decomposition (sSVD), block-circulant singular value decomposition (bSVD), Tikhonov, TTV, and our proposed TENDER. The first row is the whole brain CBF map and the second row is the closeup view of a selected region.
