ABSTRACT:
A miniature echosonometer adapted for implantation in the interior of an animal for imaging the internal structure of an organ, tissue or vessel. The echosonometer includes a receiver/transmitter circuit which is coupled to an ultrasonic transducer. Power is coupled to the echosonometer by electromagnetic induction through the animal's skin. Imaging signals from the echosonometer are electronmagnetically transmitted through the animal's skin to an external readout apparatus.
