Zusammenfassung:An interrogator system, comprising: one or more ultrasonic transducers; one or more processors; a non-transitory computer-readable storage medium storing one or more programs configured to be executed by the one or more processors, the one or more programs comprising instructions for: detecting an electrophysiological signal based on ultrasonic backscatter encoding the electrophysiological pulse emitted from at least one implantable device; and determining a location of the implantable device relative to the one or more ultrasonic transducers, or detecting movement of the implantable device, based on ultrasonic backscatter not responsive to the electrophysiological pulse emitted from the implantable device.
