Abstract
The present disclosure relates to computerized systems and methods for determining the location and orientation of implanted devices. Consistent with some embodiments, power levels of near-field signals are backscattered from an implanted device. The backscattered near-field signals may be detected by an ex-vivo antenna array. The determined power levels may be used to identify candidate location and orientation combinations based on a data set. The data set may be generated by calibrating the antenna array to the implanted device. A candidate location and orientation combination among the identified candidate combinations may be selected as the location and orientation of the implanted device.
