20-Ch Tx Modular Array for 7T PTX Applications

Tamer S. Ibrahim¹, Daniel Stough¹, Tiejun Zhao²

In this work, we present the design of a modular transmit head array from sets of coils with highly-coupled elements for 7T head applications. The 20-ch Tx modular array has no distinctive rotation, thus resulting in comparable field coverage in the axial plane and in the z direction. The array has been tested on 15 subjects.
