Purpose To evaluate the utility of an efficient triple velocity‐encoding (VENC) 4D flow MRI
implementation to improve velocity unwrapping of 4D flow MRI data with the same scan time …

Dual-VENC strategies have been proposed to improve the velocity-to-noise ratio in phase-
contrast MRI. However, they are based on aliasing-free high-VENC data. The aim of this …

A novel divergence-free constrained phase unwrapping method was proposed and
evaluated for 4D flow MRI. The unwrapped phase field was obtained by integrating the …

Purpose To develop and evaluate a phase unwrapping method for cine phase contrast MRI
based on graph cuts. Methods A proposed Iterative Graph Cuts method was evaluated in 10 …

In phase-contrast magnetic resonance imaging (PC-MRI), spin velocity contributes to the
phase measured at each voxel. Therefore, estimating velocity from potentially wrapped …

Purpose To develop an auto‐calibrated image reconstruction for highly accelerated multi‐
directional phase‐contrast (PC) MRI that compensates for (1) reconstruction instabilities …

Nonuniform array geometries provide freedom for increased aperture and reduced mutual
coupling. A necessary and sufficient condition is given for an array of isotropic sensor …

Purpose To characterize the effect of hepatic vessel flow using 4-dimensional (4D) flow
magnetic resonance (MR) imaging and correlate their effect on microwave ablation volumes …

This dissertation addresses two distinct topics: inference from synthetic aperture radar (SAR)
data and the application of lattice theory to array signal processing. First, we propose a …

In magnetic resonance imaging (MRI), the k-space data are samples from the continuous
Fourier transform of the underlying image. Physical and physiological limits (eg, gradient …
