Synopsis

Keywords: RF Arrays & Systems, Shims

An eight-channel transceiver 1H/19F dual-frequency 3-Tesla body array has been developed to investigate the use of a perfluorocarbon (PFC) compound for use in as diagnostic tool in the investigation of inflammation inside the human body. Dual-frequency operation enables the same coil to be used at both frequencies, which reduces scan time, improves patient comfort, and provides accurate anatomic localisation. This RF coil consists of 8 transceiver elements, with four in each posterior and anterior half. This abstract presents the electromagnetic (EM) simulations for B1+ homogenisation, SAR assessment and validation of the dual-frequency array.
