4D Computed Tomography Reconstruction from Few-Projection Data via Temporal Non-local Regularization
13 years 5 months ago
Abstract. 4D computed tomography (4D-CT) is an important modality in medical imaging due to its ability to resolve patient anatomy motion in each respiratory phase. Conventionally ...
