Journal ArticleDOI
Highly parallel volumetric imaging with a 32-element RF coil array.
Yudong Zhu,Christopher J. Hardy,Daniel K. Sodickson,Randy Otto John Giaquinto,Charles L. Dumoulin,Gontran Kenwood,Thoralf Niendorf,Hubert Lejay,Charles A. McKenzie,Michael A. Ohliger,Neil M. Rofsky +10 more
TL;DR: A 32‐element receive‐coil array and a volumetric paradigm that address the SNR challenge at high accelerations by maximally exploiting multidimensional acceleration in conjunction with noise averaging is presented.
Journal ArticleDOI
Designing multichannel, multidimensional, arbitrary flip angle RF pulses using an optimal control approach.
TL;DR: The multidimensional multichannel RF pulse design is formulating as an optimal control problem with multiple controls based directly on the Bloch equation to improve the spatial localization or homogeneity of the magnetization profiles.
Journal ArticleDOI
Toward single breath-hold whole-heart coverage coronary MRA using highly accelerated parallel imaging with a 32-channel MR system.
Thoralf Niendorf,Thoralf Niendorf,Thoralf Niendorf,Christopher J. Hardy,Randy Otto John Giaquinto,Patrick Gross,Harvey E. Cline,Yudong Zhu,Gontran Kenwood,Shmuel E. Cohen,Aaron K. Grant,Sanjay Joshi,Neil M. Rofsky,Daniel K. Sodickson +13 more
TL;DR: The use of the 32‐element array in unaccelerated CMRA studies provided a baseline SNR increase of as much as 40% over conventional cardiac‐optimized phased array coils, which resulted in substantially enhanced image quality and improved delineation of the coronary arteries.
Journal ArticleDOI
Electrodynamic constraints on homogeneity and radiofrequency power deposition in multiple coil excitations.
TL;DR: This work explores electrodynamic constraints on transmit homogeneity and SAR, for both fully parallel transmission and its time‐independent special case known as radiofrequency shimming, and shows flattening or slight reduction with increasing field strength.
Journal ArticleDOI
Rapid volumetric MRI using parallel imaging with order-of-magnitude accelerations and a 32-element RF coil array: feasibility and implications

TL;DR: The highly parallel imaging approach presented here allows previously inaccessible volumetric coverage for time-sensitive MRI examinations such as contrast-enhanced MRA, and simultaneously provides a substantially simplified imaging paradigm.
