Joint partial fourier and compressed sensing reconstruction for accelerated time-of-flight MR angiography
Time-of-flight (TOF) magnetic resonance (MR) angiography is a popular tool for non-contrast-enhanced angiographic imaging of intracranial vasculature. However, strategies that lead to enhancement of inflow effects come at ...
Targeted vessel reconstruction in non-contrast-enhanced steady-state free precession angiography
(John Wiley and Sons Ltd, 2016)
Image quality in non-contrast-enhanced (NCE) angiograms is often limited by scan time constraints. An effective solution is to undersample angiographic acquisitions and to recover vessel images with penalized reconstructions. ...
Statistically segregated k-space sampling for accelerating multiple-acquisition MRI
A central limitation of multiple-acquisition magnetic resonance imaging (MRI) is the degradation in scan efficiency as the number of distinct datasets grows. Sparse recovery techniques can alleviate this limitation via ...
Huber function based reconstruction in accelerated phase-cycled bSSFP acquisitions for increased detection performance
Balanced steady-state free precession imaging suffers from irrecoverable signal losses, called banding artifacts. A common way to alleviate banding artifacts without sacrificing scan-efficiency is to use multiple-acquisition ...
Profile-encoding reconstruction for multiple-acquisition balanced steady-state free precession imaging
(John Wiley and Sons Inc., 2017)
Purpose: The scan-efficiency in multiple-acquisition balanced steady-state free precession imaging can be maintained by accelerating and reconstructing each phase-cycled acquisition individually, but this strategy ignores ...
