Claim 0:
1. A system for 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 system comprising:
an image reconstruction processor configured to provide a reconstructed ultrasound image corresponding to the image plane defined by the ultrasound imaging probe; and
a position determination processor configured to:
detect a maximum intensity ultrasound signal from among ultrasound signals transmitted between the ultrasound imaging probe and an ultrasound transducer attached to the interventional device,
compute a position of the ultrasound transducer relative to the image plane based on a time of flight of the maximum detected intensity ultrasound signal,
indicate the computed position of the ultrasound transducer in the reconstructed ultrasound image, and
suppress 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.
