Imaging of human sized subjects at ultra high fields, such as 7T, suffers intrinsically from the interaction of the B1 field with the dielectric human tissue. B1 shimming and TX-Sense have been proposed to improve the homogeneity of the B1 field. With the exception of the 3 channel system of Ullman et al., previous parallel excitation work has been limited to modelling with a single TX channel system. We demonstrate a modular approach to adding TX channels to a clinical scanner. The system is also well suited to multinuclear spectroscopy and ASL experiments utilizing multiple labelling coils, as well as dynamic shimming with up to 21 shim channels.
