Least Squares Optimal Density Compensation for the Gridding Non-uniform Discrete Fourier Transform
Nicholas Dwork, Daniel O'Connor, Ethan M. I. Johnson +4
The Gridding algorithm has shown great utility for reconstructing images from non-uniformly spaced samples in the Fourier domain in several imaging modalities. Due to the non-unifo…
Slide-free MUSE Microscopy to H&E Histology Modality Conversion via Unpaired Image-to-Image Translation GAN Models
Tanishq Abraham, Andrew Shaw, Daniel O'Connor +2
MUSE is a novel slide-free imaging technique for histological examination of tissues that can serve as an alternative to traditional histology. In order to bridge the gap between M…
Multi-coil Magnetic Resonance Imaging with Compressed Sensing Using Physically Motivated Regularization
Nicholas Dwork, Ethan M. I. Johnson, Daniel O'Connor +5
With the advent of multi-coil imaging and compressed sensing, a number of model based reconstruction algorithms have been created. They incorporate a multitude of different regular…
Fast Variable Density Poisson-Disc Sample Generation with Directional Variation
Nicholas Dwork, Corey A. Baron, Ethan M. I. Johnson +3
We present a fast method for generating random samples according to a variable density Poisson-disc distribution. A minimum threshold distance is used to create a background grid a…
Di-chromatic Interpolation of Magnetic Resonance Metabolic Imagery
Nicholas Dwork, Jeremy W. Gordon, Shuyu Tang +4
Magnetic resonance imaging with hyperpolarized contrast agents can provide unprecedented \textit{in-vivo} measurements of metabolism, but yields images that are lower resolution th…
Utilizing the Wavelet Transform's Structure in Compressed Sensing
Nicholas Dwork, Daniel O'Connor, Corey A. Baron +4
Compressed sensing has empowered quality image reconstruction with fewer data samples than previously though possible. These techniques rely on a sparsifying linear transformation.…
