| Zusammenfassung | Introduction: Controlled application of thermal dose is of major interest in thermal phenotyping, multimodal RF hyperthermia treatments, thermal targeted drug delivery and MR safety evaluations [1-3]. Thermal MR utilizes the spin excitation frequency together with dedicated RF antennas for controlled RF induced heating and imaging in an integrated system [4-5]. Operating the MR power amplifier for RF heating and MRI simultaneously requires customized transmit/receive (TxRx) switches, which can protect the preamps from high peak powers and withstand high average power of )50-100W. Traditional TxRx switches commonly use pin diodes to switch between transmit and receive modes, which constraints the average power to (25W. To address this shortcoming we designed, built and evaluated a high power TxRx switch tailored for Thermal MR applications that is capable to be driven at much larger average power. |
