چکیده
vertical line for standard and motion-guided L+S reconstruction of 12.8-fold accelerated abdominal DCE radial data acquired during free-breathing. The arrows indicate temporal blurring in the standard L+S image and y-t plot, which are removed by the motion-guided L+S approach without loss of spatial resolution. Figure 1: Standard and motion-guided L+S reconstruction of 8-fold accelerated cardiac perfusion data acquired during free-breathing. The arrows indicate temporal blurring artifacts in the standard L+S images caused by misalignment among frames. 6935 Motion-guided low-rank plus sparse (L+S) reconstruction for free-breathing dynamic MRI Ricardo Otazo, Thomas Koesters, Emmanuel Candès, and Daniel K Sodickson Bernard and Irene Schwartz Center for Biomedical Imaging, Department of Radiology, New York University School of Medicine, New York, NY, United States, Departments of Mathematics and Statistics, Stanford University, Stanford, CA, United States

Low-rank plus sparse matrix decomposition for accelerated dynamic MRI with separation of background and dynamic components.
PURPOSE To apply the low-rank plus sparse (L+S) matrix decomposition model to reconstruct undersampled dynamic MRI as a superposition of background and dynamic components in various problems of clinical interest. THEORY AND METHODS The L+S model is natural to represent dynamic MRI data. Incoherence between k-t space (acquisition) and the singular vectors of L and the sparse domain of S is req...

متن کاملMotion corrected compressed sensing for free-breathing dynamic cardiac MRI.
Compressed sensing (CS) has been demonstrated to accelerate MRI acquisitions by reconstructing sparse images of good quality from highly undersampled data. Motion during MR scans can cause inconsistencies in k-space data, resulting in strong motion artifacts in the reconstructed images. For CS to be useful in these applications, motion correction techniques need to be combined with the undersam...
متن کاملA Unified Tensor Regression Framework for Calibrationless Dynamic, Multi-Channel MRI Reconstruction
TARGET AUDIENCE: Magnetic resonance image (MRI) reconstruction developers. PURPOSE: Advanced image reconstruction strategies often require explicit knowledge about the MRI acquisition system or target signal. For example, the GRAPPA [1] method for parallel MRI requires a kernel model of inter-coil k-space correlations that result from receiver sensitivity modulations; and kt-BLAST [2] requires ...
متن کاملFree Breathing Dynamic Contrast Enhanced 3D MRI with Resolved Respiratory Motion
PURPOSE: Respiratory motion is a major issue in abdominal MRI, especially for pediatric patients who have difficulty performing breath-holds. The problem is exacerbated in lengthy scans, such as for dynamic contrast enhanced (DCE) MRI. Much of the previous work has been focused on reducing respiratory motion artifacts through reconstruction correction schemes. An alternative approach is resolvi...
