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...
The Application of Diffusion- and Perfusion-Weighted Magnetic Resonance Imaging in the Diagnosis and Therapy of Acute Cerebral Infarction
Imaging Diagnosis Therapy of Acute Cerebral Infarction
2009/9/8
Diffusion- and perfusion-weighted magnetic resonance imaging (DWI and PWI) was applied for stroke diagnose in 120 acute (<48 h) ischemic stroke patients. At hyperacute (<6 h) stage, it is difficult to...
