In todays high-field systems, severe problems regarding the homogeneity of the transmission field are encountered. Most of the methods proposed to tackle these problems are multichannel methods. Recently, Time-Interleaved Acquisition of Modes (TIAMO) has been proposed to cope with B1 inhomogeneity in ultra-high-field imaging. In this work we present a simple and inexpensive hardware setup which makes it possible to use TIAMO on any single-channel Tx system while making use of the vendor-provided single-channel RF safety system. We show that with this setup 7 Tesla spin echo imaging of the pelvis is possible without severe signal dropouts.
