Time‐resolved contrast‐enhanced 3D MR angiography
TLDR
An MR angiographic technique, referred to as 3D TRICKS (3D time‐resolved imaging of contrast kinetics) has been developed. Expand

Time‐resolved contrast‐enhanced imaging with isotropic resolution and broad coverage using an undersampled 3D projection trajectory
TLDR
Time‐resolved contrast‐enhanced 3D MR angiography (MRA) methods have gained in popularity but are still limited by the tradeoff between spatial and temporal resolution. Expand

PC VIPR: a high-speed 3D phase-contrast method for flow quantification and high-resolution angiography.
BACKGROUND AND PURPOSE Three-dimensional phase-contrast (3DPC) is limited by long imaging times, limited coverage, flow artifacts, and the need to perform multiple additional 2D examinations (2DPC)Expand

Highly constrained backprojection for time‐resolved MRI
TLDR
We present here a simple non‐iterative unfiltered backprojectION algorithm that incorporates the idea of a composite image consisting of portions or all of the acquired data to constrain the backprojection process. Expand

Improved 3D phase contrast MRI with off‐resonance corrected dual echo VIPR
TLDR
Dual echo PC VIPR is a self contained solution to address both, off-resonance and trajectories errors, with the added benefit of reducing eddy-current errors that generally causes errors in phase contrast velocimetry. Expand

Noise reduction in spectral CT: reducing dose and breaking the trade-off between image noise and energy bin selection.
PURPOSE Our purpose was to reduce image noise in spectral CT by exploiting data redundancies in the energy domain to allow flexible selection of the number, width, and location of the energy bins. Expand

Coronary MRI with a Respiratory Feedback Monitor: The 2D Imaging Case
The inability to return the heart to the same position for all breath‐holds during 2D coronary MR imaging can result in imaging different locations than desired. This can lead to problems such as (i)Expand

Dynamic PET Denoising with HYPR Processing
TLDR
We introduced the modified HYPR algorithm (the HYPR method constraining the backprojections to local regions of interest [HYPR-LR]) for the processing of dynamic PET studies. Expand

Undersampled projection reconstruction applied to MR angiography
Undersampled projection reconstruction (PR) is investigated as an alternative method for MRA (MR angiography). In conventional 3D Fourier transform (FT) MRA, resolution in the phase‐encodingExpand

Improved waveform fidelity using local HYPR reconstruction (HYPR LR)
The recently introduced HYPR (HighlY constrained backPRojection) method allows reconstruction of serial images from highly undersampled data. In HYPR, individual timeframes are obtained viaExpand
