Claim 9:
10. A method of determining a position of an interventional device relative to an image plane defined by an ultrasound imaging probe of a beamforming ultrasound imaging system, the method comprising:
generating a reconstructed ultrasound image corresponding to the image plane defined by the ultrasound imaging probe;
detecting a maximum intensity ultrasound signal from among ultrasound signals transmitted between the ultrasound imaging probe and an ultrasound transducer attached to the interventional device;
computing a position of the ultrasound transducer relative to the image plane based on a time of flight of the maximum detected intensity ultrasound signal;
indicating the computed position of the ultrasound transducer in the reconstructed ultrasound image; and
suppressing entirely indication of the position of the ultrasound transducer in the reconstructed ultrasound image if a rate of change of the computed position exceeds a first predetermined rate.
