HIGH SPATIAL AND TEMPORAL RESOLUTION DYNAMIC CONTRAST-ENHANCED MAGNETIC RESONANCE IMAGING |
摘要 |
<p>A method for high spatial and temporal resolution dynamic contrast enhanced magnetic resonance imaging using a random subsampled Cartesian k-space using a Poisson-disk random pattern acquisition strategy and a compressed sensing reconstruction algorithm incorporating magnitude image subtraction is presented. One reconstruction uses a split-Bregman minimization of the sum of the L1 norm of the pixel-wise magnitude difference between two successive temporal frames, a fidelity term and a total variation (TV) sparsity term.</p> |
