Publication number: 20240065773Abstract: The present invention relates to guidance during a medical intervention. In order to provide an improved navigation support with a facilitated setup, a system (10) for navigation support is provided. An image data input (12) receives a plurality of acquired 2D X-ray images of a subject's body from different angles. A set of markers, which are visible in X-ray images and which are detectable by a navigation system, is assigned to the subject. A marker detecting arrangement (16) is provided that detects a current spatial location of the markers assigned to the subject. A data processor (14) reconstructs a 3D volume of the subject based on the plurality of 2D X-ray images. At least a part of the markers is arranged outside the volume covered by the reconstructed 3D volume of the subject, while the markers are visible in the 2D X-ray images.Type: ApplicationFiled: December 28, 2021Publication date: February 29, 2024Inventors: RONALDUS FREDERIK JOHANNES HOLTHUIZEN, ROBERT JOHANNES FREDERIK HOMAN, JARICH WILLEM SPLIETHOFF, BERNARDUS HENDRIKUS WILHELMUS HENDRIKS, PETER GEORGE VAN DE HAAR, JOHANNEKE GERRIGJE GROEN, JAN RONGEN, EDWARD VUURBERG, JOHAN JULIANA DRIES, CHRISTIAN REICH, KESHAV SIMHADRI

Patent number: 11911207Abstract: Various embodiments of the present disclosure include a C-arm registration system employing a controller (70) for registering a C-arm (60) to a X-ray ring marker (20). The X-ray ring marker (20) includes a coaxial construction of a chirp ring (40) and a centric ring (50) on an annular base (30). In operation, the controller (70) acquires a baseline X-ray image illustrative of the X-ray ring marker (20) within a baseline X-ray projection by the C-arm (60) at a baseline imaging pose, derives baseline position parameters of the X-ray ring marker (20) within the baseline X-ray projection as a function of an illustration of the centric ring (50) within the baseline X-ray image, and derives a baseline twist parameter of the X-ray ring marker (20) within the baseline X-ray projection as a function of the baseline position parameters and of an illustration of the chirp ring (40) within the baseline X-ray image.Type: GrantFiled: March 25, 2020Date of Patent: February 27, 2024Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Alexandru Patriciu, Alyssa Torjesen, Molly Lara Flexman, Ashish Sattyavrat Panse, Marcin Arkadiusz Balicki, Ronaldus Frederik Johannes Holthuizen

Publication number: 20230240758Abstract: The invention relates to a system (8) for assisting a user in placing a penetrating device in tissue like a pedicle screw (7) in a vertebra’s pedicle. The system generates a virtual view (20) from a penetrating device tip perspective within the tissue in the direction of a path (21) through a model of the tissue. The virtual view is generated based on tracking information indicating a pose of the penetrating device, the model and the path, wherein the virtual view is configured such that it indicates a direction in which the user should move the penetrating device while placing it in the tissue. For instance, it can show a virtual tunnel (801) which is arranged along the path. If a user like a surgeon is provided with such a virtual view, the user can position the penetrating device along the path with a significantly increased accuracy.Type: ApplicationFiled: June 29, 2021Publication date: August 3, 2023Inventors: JARICH WILLEM SPLIETHOFF, BERNARDUS HENDRIKUS WILHELMUS HENDRIKS, DRAZENKO BABIC, JOHANNEKE GERRIGJE GROEN, CHRISTIAN REICH, RONALDUS FREDERIK JOHANNES HOLTHUIZEN, ROBERT JOHANNES FREDERIK HOMAN
