Patent ID: 11872075

Abstract:
System (10) for determining a position of an interventional device (11) respective an image plane (12) defined by an ultrasound imaging probe (13). The position is determined based on ultrasound signals transmitted between the ultrasound imaging probe (13) and an ultrasound transducer (15) attached to the interventional device (11). An image reconstruction unit (IRU) provides a reconstructed ultrasound image (RUI). A position determination unit (PDU) computes a position (LAPTOFSmax, θIPA) of the ultrasound transducer (15) respective the image plane (12). The position determination unit (PDU) indicates the computed position (LAPTOFSmax, θIPA) in the reconstructed ultrasound image (RUI). The position determination unit (PDU) suppresses the indication of the computed position (LAPTOFSmax, θIPA) under specified conditions relating to the computed position (LAPTOFSmax, θIPA) and the ultrasound signals.
