PET-MRI Joint Reconstruction by Joint Sparsity Based Tight Frame Regularization
Jae Kyu Choi, Chenglong Bao, Xiaoqun Zhang
Recent technical advances lead to the coupling of PET and MRI scanners, enabling to acquire functional and anatomical data simultaneously. In this paper, we propose a tight frame b…
An Edge Driven Wavelet Frame Model for Image Restoration
Jae Kyu Choi, Bin Dong, Xiaoqun Zhang
Wavelet frame systems are known to be effective in capturing singularities from noisy and degraded images. In this paper, we introduce a new edge driven wavelet frame model for ima…
Dipole Incompatibility Related Artifacts in Quantitative Susceptibility Mapping
Liangdong Zhou, Jae Kyu Choi, Youngwook Kee +2
Artifacts in quantitative susceptibility mapping (QSM) are analyzed to establish an optimal design criterion for QSM inversion algorithms. The magnetic field data is decomposed int…
