We present models for wirelessly powering implants using the transmit RF excitation for MRI. Detailed models were developed for all hardware components of the transmit chain, including actual MRI sequences. Candidate pulse sequences were compared to predict how wireless powering could operate synchronously with imaging. The methods are useful in designing and optimizing wireless powering inside the MRI scanner.
