Synopsis

Keywords: RF Arrays & Systems, Body

The purpose of this study is to compare two different coil array designs for prostate imaging. We compared an in-house developed 8ch^pTx/Rx micro stripline element coil array with meanders to a recently introduced, commercially available 8ch^pTx/Rx coil array based on fractionated dipoles for ¹H prostate imaging at 7T. Both coil arrays showed comparable results in the phantom and in vivo examinations. The commercially available coil array performs slightly better in the region of the prostate and is well suited for future prostate imaging at 7T.
