Abstract: | An ultrasound imaging system, and method for using the same, includes an active transducer and transmitter for producing a pulse of ultrasonic energy steerable in the direction of one or more targets. The active transducer is also coupled to a receiver for receiving an echo of the pulse returned from each target. A second, passive phased-array transducer acts as another receiver and is electronically steerable to receive echoes of the pulse returned from each target. A controller coordinates steering of the active and passive transducer “listening” directions toward each target, and a signal processor processes the echoes received by the receivers from each target to form a composite image of the target. A second passive transducer can be added to further enhance the imaging resolution. In preferred embodiments, the active and passive transducers are electronically steered phased array transducers. |
