Wireless power transfer is a method that could be used to power wireless MRI coils, as well as send a synchronization signal for wireless coils. Our proposed system is capable of delivering power inside an MRI bore without degrading the image quality, due to our use of RF gating to stop power transmission during the MRI receive time, while continuing to power the load with a storage capacitor. We are also able to continuously send a synchronization tone with minimal impact on the image quality up to a 5-7W transmission threshold.
