Bio-medical unit and system with electromagnetic power harvesting and communication

摘要

A medical system includes a transmitter unit, a bio-medical unit, and a receiver unit. The transmitter unit generates a magnetic resonance imaging signal and a downstream electromagnetic communication signal. The transmitter unit then modulates the downstream electromagnetic communication signal on the magnetic resonance imaging signal. The bio-medical unit receives the modulated magnetic resonance imaging signal and recovers, therefrom, the downstream electromagnetic communication signal. The bio-medical unit converts the downstream electromagnetic communications signal into downstream information. The bio-medical also converts upstream information into an upstream electromagnetic communication signal. The receiver unit receives the modulated magnetic resonance imaging signal and the upstream electromagnetic communication signal. The receiver unit then recovers the magnetic resonance imaging signal from the modulated magnetic resonance imaging signal and the upstream information from the upstream electromagnetic communication signal.
