Adapted Random 3D Sampling Patterns for CE-MRA
Introduction: Variable density 3D random sampling trajectories which were introduced in the context of compressed sensing [1] have great potential for subsampled CE-MR angiography techniques which deliver data sets with high contrast to noise ratio. The goal of this work was to present a parameter-free method to construct variable density sampling patterns which are tailored to angiography. Sam...
متن کاملOptimized Sampling Patterns for Random 3D Subsampling and Parallel Imaging Reconstruction by Regularized Nonlinear Inversion
A method is presented for scan time reduction in magnetic resonance imaging by combining an optimized random sampling pattern with a nonlinear reconstruction by iterative regularized Gauß-Newton. The sampling pattern is generated using a probability density function derived from the power spectrum of a reference image, which can be either taken from a pre-scan or a template. The proposed method...
متن کاملParallel imaging with nonlinear reconstruction using variational penalties.
A new approach based on nonlinear inversion for autocalibrated parallel imaging with arbitrary sampling patterns is presented. By extending the iteratively regularized Gauss-Newton method with variational penalties, the improved reconstruction quality obtained from joint estimation of image and coil sensitivities is combined with the superior noise suppression of total variation and total gener...
متن کاملHighly Undersampled 3D Golden Ratio Radial Imaging with Iterative Reconstruction
Introduction Compressed Sensing (CS) [1,2] suggests that using nonlinear reconstruction algorithms based on convex optimization an accurate signal reconstruction can be obtained from a number of samples much lower than required by the Nyquist limit. Recently, CS was demonstrated for MR imaging from undersampled data [3, 4]. Prerequisites for a good image reconstruction are the image compressibi...
متن کاملAccelerating Magnetic Resonance Imaging through Compressed Sensing Theory in the Direction space-k
Magnetic Resonance Imaging (MRI) is a noninvasive imaging method widely used in medical diagnosis. Data in MRI are obtained line-by-line within the K-space, where there are usually a great number of such lines. For this reason, magnetic resonance imaging is slow. MRI can be accelerated through several methods such as parallel imaging and compressed sensing, where a fraction of the K-space lines...
