متن کاملTime-Resolved MRA using Radial Multi-Echo Sequence and Sliding Window Reconstruction
Introduction: There have been many attempts to increase the temporal resolution of time-resolved MRA, including sliding window reconstruction (1-2), TRICKS (3), and HYPR (4). Although these techniques achieve high frame rates, each frame still contains data acquired over a long temporal window, typically longer than 10 seconds. In other words, the frames have long temporal footprints. We introd...
متن کاملHYPR PR-TRICKS: Highly Undersampled hybrid radial/Cartesian acquisition with HighlY constrained backPRojection reconstruction for time resolved MRI
INTRODUCTION In time-resolved MRI, there is a trade-off between spatial and temporal resolution due to requirement of the Nyquist theorem. Previously, we described a time-resolved hybrid radial/Cartesian acquisition, PR-TRICKS [1], which combines in-plane radially undersampled acquisition with through-plane Cartesian TRICKS acquisition to provide large undersampling factors. We have recently de...
