Modeling and Reconstruction of Mixed Functional and Molecular Patterns
Modeling Mixed Functional Molecular Patterns
2009/9/8
Functional medical imaging promises powerful tools for the visualization and elucidation of important disease-causing biological processes in living tissue. Recent research aims to dissect the distrib...
Local ROI Reconstruction via Generalized FBP and BPF Algorithms along More Flexible Curves
FBP BPF Algorithms Flexible Curves
2009/9/8
We study the local region-of-interest (ROI) reconstruction problem, also referred to as the local CT problem. Our scheme includes two steps: (a) the local truncated normal-dose projections are extende...
Comparison of Lesion Detection and Quantification in MAP Reconstruction with Gaussian and Non-Gaussian Priors
MAP Non-Gaussian Priors
2009/9/8
Statistical image reconstruction methods based on maximum a posteriori (MAP) principle have been developed for emission tomography. The prior distribution of the unknown image plays an important role ...
A Parallel Reconstruction Scheme in Fluorescence Tomography Based on Contrast of Independent Inversed Absorption Properties
Fluorescence Tomography Independent Inversed Absorption Properties
2009/9/8
Based on an independent forward model in fluorescent tomography, a parallel reconstructed scheme for inhomogeneous mediums with unknown absorption property is proposed in this paper. The method consid...
A Penalized Linear and Nonlinear Combined Conjugate Gradient Method for the Reconstruction of Fluorescence Molecular Tomography
Fluorescence Molecular Tomography A Penalized Linear
2009/9/7
Conjugate gradient method is verified to be efficient for nonlinear optimization problems of large-dimension data. In this paper, a penalized linear and nonlinear combined conjugate gradient method fo...
Reordering for Improved Constrained Reconstruction from Undersampled k-Space Data
Improved Constrained Reconstruction Undersampled k-Space Data
2009/9/4
Recently, there has been a significant interest in applying reconstruction techniques, like constrained reconstruction or compressed sampling methods, to undersampled k-space data in MRI. Here, we pro...
In-vivo coronary flow profiling based on biplane angiograms: influence of geometric simplifications on the three-dimensional reconstruction and wall shear stress calculation
In-vivo coronary flow profiling biplane angiograms
2010/2/26
We investigated the influence of two methods of lumen reconstruction, assuming circular versus elliptical cross-sections and using different resolutions for the cross-section reconstructions along the...
