ABSTRACT:
An ultrasound imaging system comprises a position location array adapted to be affixed to a surface layer of an imaging subject. The position location array comprises a plurality of electrodes disposed in a grid pattern within a flexible substrate. An imaging transducer having at least one element is operable to provide an acoustic pulse through the position location array and the surface layer in response to a driving signal and to provide a corresponding return signal in response thereto. A receiver is coupled to the imaging transducer to receive the return signal from the at least one element and provide a beamformed signal. A processor coupled to the receiver and the position location array forms an image from the beamformed signal that includes position coordinates that correspond to an intersection between the acoustic pulse and associated ones of the plurality of electrodes.
