Dual-domain projection fidelity network for sparse-view helical CT reconstruction

Abstract: Sparse-view computed tomographic (CT) image reconstruction aims to shorten scanning time, reduce radiation dose, and yield high-quality CT images simultaneously. Some researchers have developed deep learning (DL) based models for sparse-view CT reconstruction on the circular scanning trajectories. However, cone beam CT (CBCT) image reconstruction based on the circular trajectory is theoretically an ill-posed problem and cannot accurately reconstruct 3D CT images, while CBCT reconstruction of helical trajectory… Show more
