Fig. 3From: GPU-accelerated iterative reconstruction for limited-data tomography in CBCT systemsFrom left to right: reference image and reconstructed image with the FDK-method and the proposed iterative method. Top panel corresponds to the case of 60 projections covering an angular span of 360 degrees and bottom panel to the case of 45 projections covering an angular span of 150 degrees. Yellow circle in the bottom left panel shows the ROI for the SNR measurementBack to article page
