Sparse-view reconstructionCurveletTotal variationThe reconstruction from sparse-view projections is one of important problems in computed tomography limited by the availability or feasibility of a large number of projections. Total variation (TV) approaches have been introduced to improve the reconstruction ...

In the medical CT fi eld, sparse-view sampling has prac-tical implications in reducing ionizing radiation, which is harmful to people’s health, decreasing the scanning time and improving the scanning limits in many scenarios [2, 3]. In the industrial CT, when it was limited by scanning ...
Therefore, improving the spatial resolution of sparse-view CT (SVCT) is of great practical value. In this study, we proposed a deep learning-based approach for SVCT spatial resolution enhancement. The proposed method utilizes a densely connected convolutional neural network (CNN) that is further ...
Sparse-view CT reconstruction algorithms via total variation (TV) optimize the data iteratively on the basis of a noise- and artifact-reducing model, resulting in significant radiation dose reduction while maintaining image quality. However, the piecewise constant assumption of TV minimization often lead...
