Abstract:
An experimental implementation and first performance analysis of parallel spatially selective excitation with an array of transmit coils and simultaneous transmission of individual waveforms on multiple channels is presented. This technique, also known as Transmit SENSE, uses the basic idea of parallel imaging to shorten the k-space trajectories that accompany multidimensional excitation pulses, and hence shorten the duration of such pulses. So far, this concept has only been presented in simulations and semi-experimental studies since no hardware setup had been available for a full experimental realization. In this study, a hardware solution, in combination with a dedicated coil setup, is presented to overcome this limitation, and in several experiments of localized excitation and transmit field inhomogeneity compensation the practical feasibility of Transmit SENSE is demonstrated and a first performance analysis is given.
