Reducing the Sampling Burden of Fourier Sensing with a Non-rectangular Field-of-View

N Dwork, EK Englund, AJ Barker - arXiv preprint arXiv:2406.16214, 2024 - arxiv.org
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 have …

The Dependence of Parallel Imaging with Linear Predictability on the Undersampling Direction

A McManus, S Becker, N Dwork - arXiv preprint arXiv:2301.07256, 2023 - arxiv.org
Parallel imaging with linear predictability takes advantage of information present in multiple

Faster Scanning with Parallel MRI Using a Non-Rectangular Field-Of-View

N Dwork, EK Englund, AJ Barker - 2024 IEEE Conference on …, 2024 - ieeexplore.ieee.org
Conventional magnetic resonance imaging (MRI) uses a rectangular field-of-view (FOV) to
specify the sampling pattern. The full sampling pattern is a Cartesian grid that satisfies the …

Compressed Sensing with Homodyne Detection

A McManus, SR Becker, D O'Connor… - 2024 IEEE Conference …, 2024 - ieeexplore.ieee.org
