Wireless power transfer (WPT) uses two inductively
coupled coils to transmit and receive power at a
particular frequency, creating a local power source that
can be used inside a strong magnetic field. By adding
cable traps and a brick-wall filter to the system, we
minimize the RF interactions between the WPT system and
the MR scanner. As a result, our WPT system does not
change the noise floor of the MRI preamplifiers and does
not degrade the MR image quality.
