Fig. 3From: Combining dual-tree complex wavelets and multiresolution in iterative CT reconstruction with application to metal artifact reductionThe dataset and ROIs. a The metallic regions are marked red on the phantom. b The resolution of the phantom, from which the sinogram is calculated, is \(1024 \times 1024\) pixels. The noisy projection data after inpainting has the resolution of \(768 \times 256\) pixels. c Region of interest (ROI) 1 consisting of the soft tissue (white) surrounding the teeth. d ROI 2 and ROI 3 correspond to the encircled areas. Each of them includes a single tooth with metallic implantBack to article page
