Well-Designed k-Space Coverage is Important for Good MRI Denoising
Jiayang Wang, Justin P. Haldar
Object: Modern computational MRI denoising approaches are often designed assuming fixed k-space coverage. This contrasts with earlier acquisition-design literature that leveraged k…

Shannon-like Interpolation with Spectral Priors and Weighted Hilbert Spaces: Beyond the Nyquist Rate
Justin P. Haldar
In this work, we draw connections between the classical Shannon interpolation of bandlimited deterministic signals and the literature on estimating continuous-time random processes…

Efficient Iterative Solutions to Complex-Valued Nonlinear Least-Squares Problems with Mixed Linear and Antilinear Operators
Tae Hyung Kim, Justin P. Haldar
We consider a setting in which it is desired to find an optimal complex vector that satisfies in a least-sq…
