Parallel excitation has a lot of application which includes B1+ inhomogeneity correction, thru plane B0 inhomogeneity correction and also localized excitation. These different techniques have different requirements in terms of the spatial sensitivity of the Tx array coil. In this work we have designed and constructed an 8 channel stripline based transmit array coil whose spatial profile is easily adaptable to the imaging needs using different Wilkinson splitter configuration and four transmit channels.
