Array-compressed parallel transmit pulse design.
PURPOSE To design array-compressed parallel transmit radiofrequency (RF) pulses and compare them to pulses designed with existing transmit array compression strategies. THEORY AND METHODS Array-compressed parallel RF pulse design is proposed as the joint optimization of a matrix of complex-valued compression weights that relate a full-channel physical array to a reduced-channel virtual array,...
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 ...

متن کاملVERSE‐guided parallel RF excitations using dynamic field correction
In parallel RF pulse design, peak RF magnitudes and specific absorption rate levels are critical concerns in the hardware and safety limits. The variable rate selective excitation (VERSE) method is an efficient technique to limit the peak RF power by applying a local-only RF and gradient waveform reshaping while retaining the on-resonance profile. The accuracy of the excitation performed by the...
متن کاملParallel excitation with an array of transmit coils.
Theoretical and experimental results are presented that establish the value of parallel excitation with a transmit coil array in accelerating excitation and managing RF power deposition. While a 2D or 3D excitation pulse can be used to induce a multidimensional transverse magnetization pattern for a variety of applications (e.g., a 2D localized pattern for accelerating spatial encoding during s...
متن کاملMinimal-SAR RF Pulse Optimization in Parallel Transmission
INTRODUCTION Parallel transmission is an emerging technique that has great potential in many applications such as reducing selective RF pulse duration and improving B1 and B0 field inhomogeneity in high fields [1-3]. A potential issue in parallel transmission is elevated RF power deposition which is characterized by the specific absorption ratio (SAR). In parallel excitation, the effect of elec...
