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, ?IPA) of the ultrasound transducer (15) respective the image plane (12). The position determination unit (PDU) indicates the computed position (LAPTOFSmax, ?IPA) in the reconstructed ultrasound image (RUI). The position determination unit (PDU) suppresses the indication of the computed position (LAPTOFSmax, ?IPA) under specified conditions relating to the computed position (LAPTOFSmax, ?IPA) and the ultrasound signals.

Abstract: 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.

An image reconstruction unit (IRU) provides a reconstructed ultrasound image (RUI). A position determination unit (PDU) computes a lateral position (LAPTOFSmax, ?IPA) of the ultrasound transducer (15) respective the image plane (12) based on a time of flight (TOFSmax) of a maximum detected intensity (ISmax) ultrasound signal. The position determination unit (PDU) also computes an out-of-plane distance (Dop) between the ultrasound transducer (15) and the image plane (12).

Abstract: A system for determining a position of an interventional device (11) respective an imaging field (B1 . . . k) corresponding to a type (T1 . . . n) of a beamforming ultrasound imaging probe (13) currently connected to an ultrasound imaging system (14). The position is determined based on ultrasound signals transmitted between the beamforming 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) corresponding to the imaging field (B1 . . . k). A position determination unit (PDU) receives input indicative of the type (T1 . . . k) of the beamforming ultrasound imaging probe (13) currently connected to the ultrasound imaging system (14). The position determination unit (PDU) also computes a position (LAPTOFFSmax, ?IPA) of the ultrasound transducer (15) respective the imaging field (B1 . . . k).
