SPIRiT Regularization: Parallel MRI with a Combination of Sensitivity Encoding and Linear Predictability
Nicholas Dwork, Alex McManus, Stephen Becker +1
Accelerated Magnetic Resonance Imaging (MRI) permits high quality images from fewer samples that can be collected with a faster scan. Two established methods for accelerating MRI i…
A Relaxed Primal-Dual Hybrid Gradient Method with Line Search
Alex McManus, Stephen Becker, Nicholas Dwork
The primal-dual hybrid gradient method (PDHG) is useful for optimization problems that commonly appear in image reconstruction. A downside of PDHG is that there are typically three…
Reducing the Sampling Burden of Fourier Sensing with a Non-rectangular Field-of-View
Nicholas Dwork, Erin K. Englund, Alex J. Barker
With Fourier sensing, it is commonly the case that the field-of-view (FOV), the area of space to be imaged, is known prior to reconstruction. To date, reconstruction algorithms hav…
The Dependence of Parallel Imaging with Linear Predictability on the Undersampling Direction
Alex McManus, Stephen Becker, Nicholas Dwork
Parallel imaging with linear predictability takes advantage of information present in multiple receive coils to accurately reconstruct the image with fewer samples. Commonly used a…
