| Zusammenfassung | Controlled application of thermal dose is of major interest in thermal phenotyping, multimodal RF hyperthermia treatments, thermal drug release and MR safety evaluations. An integrated RF heating system utilizes the spin excitation frequency for controlled RF induced heating and MR imaging. Operating the MR power amplifier for RF heating and MRI simultaneously requires customized transmit/receive (Tx/Rx) switches, which can protect the preamplifiers from high peak powers and withstand high average power of )50-100W. Traditional Tx/Rx switches commonly use pin diodes to switch between transmit and receive modes, which constraints the average power to. |
