Engineering of 7T transmit multi-row arrays.
In evaluation of RF transmit array coils, realistic estimation of losses were included in simulations with the aim of obtaining a better match between experimental results and numerical predictions. This required customized design of lossy circuit components, to overcome the limitation of the available built-in capabilities of current simulation tools. Some of the more time-consuming post-processing stages were relocated into Matlab, speeding post-processing by up to a factor of 100. The resulting numerical data can support the fabrication of dual row array with as many as 8 elements in each row, and elements overlapped in the Z direction.
