Limited-angle computed tomography (CT) image reconstruction is a challenging problem in the field of CT imaging. In some special applications, limited by geometric space and mechanical structure imaging system, projections can only be collected with scanning range less than 90°. We call this kind serious limited-angle ultra-limited-angle problem, which difficult to effectively alleviate traditional iterative algorithms. With development deep learning, generative adversarial network (GAN)...
Dual-energy computed tomography (DECT) provides more anatomical and functional information for image diagnosis. Presently, the popular DECT imaging systems need to scan at least full angle (i.e., 360°). In this study, we propose a using complementary limited-angle (DECT-CL) technology reduce radiation dose compress spatial distribution of system. The dual-energy total is 180°, where low- high-energy range first 90° last 90°, respectively. We describe dual problem as problem, which...
Dual-energy computed tomography (DECT) has capability to improve material differentiation, but most scanning schemes require two sets of full-scan measurements at different x-ray spectra, limiting its application imaging system with incomplete scan. In this study, using one half-scan and a second limited-angle scan, we propose DECT reconstruction method by exploiting the consistent information gradient images high- low-energy which relaxes requirement data acquisition DECT. Based on theory...
Spin-coated films are usually polycrystalline or amorphous, while some special materials such as lead iodide (PbI2) and inorganic perovskite could be deposited onto a variety of single-crystal substrates by spin coating obtaining highly oriented films. Herein, we report an effective method for depositing textured PbI2 CsPbI2Br films—via coating. An unexpected high-quality film with uniform out-plane orientation the {001} plane was on gallium nitride substrate, which benefited from...
3D Gaussian Splatting (3DGS) has emerged as a promising approach for scene representation, offering reduction in computational overhead compared to Neural Radiance Fields (NeRF). However, 3DGS is susceptible high-frequency artifacts and demonstrates suboptimal performance under sparse viewpoint conditions, thereby limiting its applicability robotics computer vision. To address these limitations, we introduce SVS-GS, novel framework Sparse Viewpoint Scene reconstruction that integrates...
Due to the hardware constraints of Computed Tomography (CT) imaging, acquiring high-resolution (HR) CT images in clinical settings poses a significant challenge. In recent years, convolutional neural networks have shown great potential super-resolution (SR) problems. However, reconstruction results many deep learning-based SR methods structural distortion and detail ambiguity. this paper, new network based on generative adversarial learning is proposed. The consists gradient branch branch....
Computed Tomography (CT) has been used in many fields. Practical misalignment of the actual CT system causes geometric artifacts reconstructed images, which severely degrades image quality. Geometric artifact evaluation provides a reliable basis for subsequent correction. Some characteristics such as entropy and sharpness, are often to measure severity artifacts, but they limited generality accuracy. Convolutional neural network (CNN) excellent feature learning capabilities is well...
Spectral computed tomography (spectral CT) is an emerging imaging technology that capable of distinguishing material properties. However, the difficulty decomposition process intensified by nonlinearity measurements and ill-conditioned problem, particularly when number materials energies do not match. Therefore, key issue in spectral CT to design improved algorithm accurate decomposition. This study proposes a one-step multi-material combines statistical reconstruction model with...
