Pixel TACs of the phantom (solid) and of the images reconstructed by using (a) FBFIR-Hann, (b) FBFIR-PCA, and (c) LRME-STIR, respectively, from the noisy data contaminated with 20% Gaussian white noise. Blue, red, green, and black correspond to the pixels marked by A, B, C, and D in Fig. 1, respectively.
