  author={Emilien Valat and Katayoun Farrahi and Thomas Blumensath},
—We address the problem of reconstructing X-Ray tomographic images from scarce measurements by interpolating missing acquisitions using a self-supervised approach. To do so, we train shallow neural networks to combine two neighbouring acquisitions into an estimated measurement at an intermediate angle. This procedure yields an enhanced sequence of measurements that can be reconstructed using standard methods, or further enhanced using regularisation approaches. Unlike methods that improve the… 



Cycloidal CT with CNN-based sinogram completion and in-scan generation of training data

It is demonstrated that high-quality images can be reconstructed by applying the recently proposed Mixed Scale Dense (MS-D) convolutional neural network (CNN) to this task, and a novel training approach by which training data are acquired as part of each scan, thus removing the need for large sets of pre-existing reference data.

Learned Primal-Dual Reconstruction

We propose the Learned Primal-Dual algorithm for tomographic reconstruction. The algorithm accounts for a (possibly non-linear) forward operator in a deep neural network by unrolling a proximal

Arbitrarily large tomography with iterative algorithms on multiple GPUs using the TIGRE toolbox

Sinogram upsampling using Primal-Dual UNet for undersampled CT and radial MRI reconstruction

The proposed Primal-Dual UNet improves the overall image quality, but also improves the image quality for the regions-of-interest: liver, kidneys, and spleen; as well as generalises better than the baselines in presence of a needle.

Simultaneous Algebraic Reconstruction Technique (SART): A Superior Implementation of the Art Algorithm

This implementation of the Algebraic Reconstruction Technique appears to have a computational advantage over the more traditional implementation of ART and potential applications include image reconstruction in conjunction with ray tracing for ultrasound and microwave tomography.

U-Net: Convolutional Networks for Biomedical Image Segmentation

It is shown that such a network can be trained end-to-end from very few images and outperforms the prior best method (a sliding-window convolutional network) on the ISBI challenge for segmentation of neuronal structures in electron microscopic stacks.

Super SloMo: High Quality Estimation of Multiple Intermediate Frames for Video Interpolation

This work proposes an end-to-end convolutional neural network for variable-length multi-frame video interpolation, where the motion interpretation and occlusion reasoning are jointly modeled.

SIPID: A deep learning framework for sinogram interpolation and image denoising in low-dose CT reconstruction

This work proposes a hybrid deep learning approach that combines sinogram interpolation with image denoising, referred to as SIPID, and highlights that the design of sinograms interpolation network can be a promising component in CT reconstruction, since it can also seamlessly fit to all kinds of image denoing networks.

TIGRE: a MATLAB-GPU toolbox for CBCT image reconstruction

The Tomographic Iterative GPU-based Reconstruction (TIGRE) Toolbox, a MATLAB/CUDA toolbox for fast and accurate 3D x-ray image reconstruction, is presented and an overview of the structure and techniques used in the creation of the toolbox is presented.

Quantitative Computed Tomographic Descriptors Associate Tumor Shape Complexity and Intratumor Heterogeneity with Prognosis in Lung Adenocarcinoma

Two CT features developed to quantitatively describe lung adenocarcinomas by scoring tumor shape complexity and intratumor density variation by scoring convexity and entropy ratio in routinely obtained diagnostic CT scans were found to be descriptive and demonstrated the link between imaging characteristics and patient survival.
