Abstract
Medical apparatus includes an invasive probe, for insertion into a body of a living subject. An ultrasonic subsystem includes an ultrasonic transducer contained in the probe and image processing circuitry, which is located outside the probe and is coupled to communicate with the ultrasonic transducer in the probe. A position sensing subsystem includes a position transducer contained in the probe and position tracking circuitry, which is located outside the probe and is coupled to communicate with the position transducer so as to determine position coordinates of the ultrasonic transducer in the body. The position sensing subsystem is electrically isolated from the ultrasonic subsystem.
