Sparse MRI: The application of compressed sensing for rapid MR imaging
TLDR
Practical incoherent undersampling schemes are developed and analyzed by means of their aliasing interference and demonstrate improved spatial resolution and accelerated acquisition for multislice fast spin‐echo brain imaging and 3D contrast enhanced angiography.
Compressed Sensing MRI
TLDR
The authors emphasize on an intuitive understanding of CS by describing the CS reconstruction as a process of interference cancellation, and there is also an emphasis on the understanding of the driving factors in applications.
SPIRiT: Iterative self‐consistent parallel imaging reconstruction from arbitrary k‐space
TLDR
A new approach to autocalibrating, coil‐by‐coil parallel imaging reconstruction, is presented, a generalized reconstruction framework based on self‐consistency that can accurately reconstruct images from arbitrary k‐space sampling patterns.
Control over brain activation and pain learned by using real-time functional MRI.
TLDR
These findings show that individuals can gain voluntary control over activation in a specific brain region given appropriate training, that voluntary controlover activation in rACC leads to control over pain perception, and that these effects were powerful enough to impact severe, chronic clinical pain.
ESPIRiT—an eigenvalue approach to autocalibrating parallel MRI: Where SENSE meets GRAPPA
TLDR
The purpose of this work is to clarify the relationship of SENSE and GRAPPA and to develop and evaluate an improved algorithm.
Parameter relations for the Shinnar-Le Roux selective excitation pulse design algorithm [NMR imaging].
An overview of the Shinnar-Le Roux (SLR) algorithm is presented. It is shown how the performance of SLR pulses can be very accurately specified analytically. This reveals how to design a pulse that
Calibrationless parallel imaging reconstruction based on structured low‐rank matrix completion
A calibrationless parallel imaging reconstruction method, termed simultaneous autocalibrating and k‐space estimation (SAKE), is presented. It is a data‐driven, coil‐by‐coil reconstruction method that
SEMAC: Slice encoding for metal artifact correction in MRI
TLDR
The efficacy of the SEMAC technique in eliminating metal‐induced distortions with feasible scan times is validated in phantom and in vivo spine and knee studies.
Saturated double‐angle method for rapid B1+ mapping
TLDR
A new method is presented for highly rapid B1+ magnitude mapping that combines the double angle method with a B1‐insensitive magnetization‐reset sequence such that the choice of repetition time (TR) is independent of T1 and with a multislice segmented (spiral) acquisition to achieve volumetric coverage with adequate spatial resolution in a few seconds.
