Patent number: 12004899Abstract: 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.Type: GrantFiled: June 16, 2022Date of Patent: June 11, 2024Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Hendrik Roelof Stapert, Mustafa Hakan Gökgürler, Jeroen Kortsmit, Stefan Van De Pas

Patent number: 11986339Abstract: 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 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).Type: GrantFiled: August 2, 2019Date of Patent: May 21, 2024Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Mischa Megens, Hendrik Roelof Stapert, Mustafa Hakan Gokgurler, Stefan Van De Pas, Jeroen Kortsmit, Franciscus Hendrikus Van Heesch, Harm Jan Willem Belt, Ameet Kumar Jain, Kunal Vaidya
