Parallel transmission for magnetic resonance imaging on a 9.4 Tesla Human System.
… of this thesis, including the implementation of spoke trajectory based transmit excitation with 16 channels at 9.4T, a fast 2D B1 mapping technique and in-depth simulation of SAR in the human brain with multi transmission.

Design of multidimensional radiofrequency pulses in magnetic resonance imaging
… design of gradient and RF waveforms to shorten spoke trajectory based RF pulses in parallel excitation. The joint design problem is formulated as an optimal spoke selection problem and is solved using a greedy algorithm. Simulation and experimental results demonstrate that the proposed method is …
