1. A controller for indicating a position of an interventional device feature, the system comprising:
an image reconstruction processor configured to provide a reconstructed ultrasound image corresponding to an image plane defined by an ultrasound imaging probe of a beamforming ultrasound imaging system;
a position determination processor configured to (i) compute a position of a ultrasound transducer respective the image plane based on ultrasound signals transmitted between the ultrasound imaging probe and the ultrasound transducer, wherein the ultrasound transducer is attached to an interventional device at a predetermined distance from an interventional device feature attached to the interventional device, and (ii) project the position of the ultrasound transducer onto the image plane;
an icon providing processor configured to provide a first icon indicative of a circular zone with a radius corresponding to the predetermined distance between the ultrasound transducer and the interventional device feature; and
an image fusion processor configured to provide a fused image comprising the reconstructed ultrasound image and the first icon, wherein the image fusion processor is configured to provide the fused image by: (i) locating, in the reconstructed ultrasound image, an insertion point corresponding to the projected position of the ultrasound transducer onto the image plane and (ii) centering the first icon at the insertion point so that the first icon indicates possible positions of the interventional device feature within the image plane.
