| Zusammenfassung | In this work, we implement a fast and accurate safety monitoring and prediction for pTx based mitigation of implant heating using fast, cheap and easy to implement rms sensors. The proof of concept is demonstrated with a guidewire substitute in an 8-channel pTx RF coil setup at 300MHz. The signals from the field sensor and temperature sensor at the guidewire tip correlated well. The pTx mitigation obtained within 25.6ms showed significant heating reduction verified by temperature measurements. The method does not require additional simulations or in vitro testing and is potentially applicable in a patient and exam specific clinical setting.
