The present invention relates to a system for indicating a position of an interventional device feature (11a) of an interventional device (11) respective an image plane (12) defined by an ultrasound imaging probe (18) of a beamforming ultrasound imaging system (15) in which the position of the interventional device feature (11a) is determined based on ultrasound signals transmitted between the ultrasound imaging probe (18) and an ultrasound transducer (16) attached to the interventional device at a predetermined distance (Lp) from the interventional device feature (11a). An icon providing unit (IPU) provides a first icon (Cde) indicative of a circular zone with a radius corresponding to the predetermined distance (Lp). The first icon (Cde) is displayed in a fused image that includes a reconstructed ultrasound image (RUI) from the beamforming ultrasound imaging system.
