Close-up views for comparison of lung region of interests reconstructed by different algorithms. The gray level images are the magnified lung ROI CT images in the red box in Fig. 1. The corresponding absolute difference images are shown in color. From top to bottom are the reference images reconstructed from full-dose projections by SART and the low-dose images reconstructed by SART, TV, LRTV, TDL and LRTP methods, respectively. ROI Region of interest; CT Computed tomography; TV Total variation; LRTV Low rand total variation; TDLTensor dictionary learning; SART Simultaneous algebraic reconstruction technique; LRTP Low rank texture prior
