A three-dimensional dual-domain deep network for high-pitch and sparse helical CT reconstruction
Wei Wang, Xiang-Gen Xia, Chuanjiang He +2
In this paper, we propose a new GPU implementation of the Katsevich algorithm for helical CT reconstruction. Our implementation divides the sinograms and reconstructs the CT images…
A New Weighting Scheme for Fan-beam and Circle Cone-beam CT Reconstructions
Wei Wang, Xiang-Gen Xia, Chuanjiang He +4
In this paper, we first present an arc based algorithm for fan-beam computed tomography (CT) reconstruction via applying Katsevich's helical CT formula to 2D fan-beam CT reconstruc…
A model-guided deep network for limited-angle computed tomography
Wei Wang, Xiang-Gen Xia, Chuanjiang He +4
In this paper, we first propose a variational model for the limited-angle computed tomography (CT) image reconstruction and then convert the model into an end-to-end deep network.W…
A deep network for sinogram and CT image reconstruction
Wei Wang, Xiang-Gen Xia, Chuanjiang He +4
A CT image can be well reconstructed when the sampling rate of the sinogram satisfies the Nyquist criteria and the sampled signal is noise-free. However, in practice, the sinogram…
