Improved excitation fidelity in cardiac imaging with 2-spoke parallel excitation at 7 Tesla
Background Cardiac MRI may greatly benefit from ultra high field (UHF) providing higher SNR and intrinsic contrast. But shorter RF wavelength yields transmit B1 (B1+) heterogeneity and contrast variations through the heart. These can be addressed by parallel transmission (pTX) using multispoke RF pulses as previously shown in other organs. However, applying pTX in cardiac MRI at 7T is challengi...

متن کاملRobust Parallel Excitation Pulse Design
Introduction Parallel excitation employs multiple transmit channels and coils, each driven by independent waveforms, to afford the pulse designer an additional spatial encoding mechanism, i.e., transmit sensitivity encoding, that complements gradient encoding. However, in contrast to parallel reception, parallel excitation requires individual high-power amplifiers for each transmit channel, whi...
متن کاملFast joint design method for parallel excitation radiofrequency pulse and gradient waveforms considering off-resonance.
A fast parallel excitation pulse design algorithm to select and to order phase-encoding (PE) locations (also known as "spokes") of an Echo-Volumar excitation k-space trajectory considering B(0) field inhomogeneity is presented. Recently, other groups have conducted research to choose optimal PE locations, but the potential benefit of considering B(0) field inhomogeneity during PE location selec...
متن کاملRF Pulse Design for Parallel Excitation
1. Introduction Parallel excitation has been introduced as a means of accelerating multi-dimensional, spatially-selective excitation using multiple transmit coils, each driven by a unique RF pulse (1,2). In a manner analogous to parallel imaging, parallel excitation allows the use of a reduced excitation k-space trajectory (7) to achieve a desired excitation pattern, by exploiting the blurring ...
