Progressive Magnetic Resonance Image Reconstruction Based on Iterative Solution of a Sparse Linear System
Image Reconstruction Sparse Linear System
2009/9/8
Image reconstruction from nonuniformly sampled spatial frequency domain data is an important problem that arises in computed imaging. Current reconstruction techniques suffer from limitations in their...
Extending Three-Dimensional Weighted Cone Beam Filtered Backprojection (CB-FBP) Algorithm for Image Reconstruction in Volumetric CT at Low Helical Pitches
CB-FBP Image Reconstruction
2009/9/8
A three-dimensional (3D) weighted helical cone beam filtered backprojection (CB-FBP) algorithm (namely, original 3D weighted helical CB-FBP algorithm) has already been proposed to reconstruct images f...
We propose two variable weighted iterative reconstruction algorithms (VW-ART and VW-OS-SART) to improve the algebraic reconstruction technique (ART) and simultaneous algebraic reconstruction technique...
Improved Image Fusion in PET/CT Using Hybrid Image Reconstruction and Super-Resolution
Improved Image Fusion PET/CT
2009/9/8
Purpose. To provide PET/CT image fusion with an improved PET resolution and better contrast ratios than standard reconstructions. Method. Using a super-resolution algorithm, several PET acquisitions w...
Cone-Beam Composite-Circling Scan and Exact Image Reconstruction for a Quasi-Short Object
Quasi-Short Object Cone-Beam Composite-Circling Scan
2009/9/4
Here we propose a cone-beam composite-circling mode to solve the quasi-short object problem, which is to reconstruct a short portion of a long object from longitudinally truncated cone-beam data invol...
Currently, 3D cone-beam CT image reconstruction speed is still a severe limitation for clinical application. The computational power of modern graphics processing units (GPUs) has been harnessed to pr...
