Sparse-view computed tomography image reconstruction via a combination of L(1) and SL(0) regularization.
Low-dose computed tomography reconstruction is an important issue in the medical imaging domain. Sparse-view has been widely studied as a potential strategy. Compressed sensing (CS) method has shown great potential to reconstruct high-quality CT images from sparse-view projection data. Nonetheless, low-contrast structures tend to be blurred by the total variation (TV, L1-norm of the gradient im...
متن کاملRandomized Iterative Reconstruction for Sparse View X-ray Computed Tomography
With the availability of more powerful computers, iterative reconstruction algorithms are the subject of an ongoing work in the design of more efficient reconstruction algorithms for X-ray computed tomography. In this work, we show how two analytical reconstruction algorithms can be improved by correcting the corresponding reconstructions using a randomized iterative reconstruction algorithm. T...
متن کاملSplit-Bregman-based sparse-view CT reconstruction
Total variation minimization has been extensively researched for image denoising and sparse view reconstruction. These methods show superior denoising performance for simple images with little texture, but result in texture information loss when applied to more complex images. It could thus be beneficial to use other regularizers within medical imaging. We propose a general regularization metho...
متن کاملCompressive Sensing Reconstruction for Sparse 2D Data
In this paper we study the compressive sensing effects on 2D signals exhibiting sparsity in 2D DFT domain. A simple algorithm for reconstruction of randomly under-sampled data is proposed. It is based on the analytically determined threshold that precisely separates signal and non-signal components in the 2D DFT domain. The algorithm operates fast in a single iteration providing the accurate si...
متن کاملSparse Image Reconstruction in Diffuse Optical Tomography: An Application of Compressed Sensing
In this paper we study the application of Compressed Sensing (CS) framework for optical tomography based on the Rytov approximation to the heterogeneous photon diffusion equation. Simulations are performed on a sample system to validate and compare inverse image reconstructions with l1-regularization (CS) and Singular Value Decomposition (SVD) respectively. Potential benefits and shortcomings o...
