Patent number: 12211147Abstract: The invention relates to a system and computer-implemented method for enabling correction of a segmentation of an anatomical structure in 3D image data. The segmentation may be provided by a mesh which is applied to the 3D image data to segment the anatomical structure. The correction may for example involve a user directly or indirectly selecting a mesh part, such as a mesh point, that needs to be corrected. The behaviour of the correction, e.g., in terms of direction, radius/neighbourhood or strength, may then be dependent on the mesh normal direction, and in some embodiments, on a difference between the mesh normal direction and the orientation of the viewing plane.Type: GrantFiled: December 21, 2020Date of Patent: January 28, 2025Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Alexandra Groth, Frank Michael Weber, Jochen Peters, Rolf Jürgen Weese

Publication number: 20240415493Abstract: A method is provided for adapting a 3D field of view (FOV) in ultrasound data acquisition so as to minimize the FOV volume in a manner that is controlled and precise. The method comprises defining a volumetric region across which 3D ultrasound data is desired, and then adapting the data acquisition field of view (FOV) in dependence upon the defined volumetric region, to encompass the region. This is achieved based on adapting a scan line length (or scan depth) of each individual scan line based on the defined volumetric region. In some embodiments, the volumetric region may be defined based on anatomical segmentation of a reference ultrasound dataset acquired in an initial step, and setting the volumetric region in dependence upon boundaries of an identified object of interest. The volumetric region may in a subset of embodiments be set as the region occupied by a detected anatomical object of interest.Type: ApplicationFiled: November 8, 2022Publication date: December 19, 2024Inventors: Irina Waechter-Stehle, Jochen Peters, Tanja Lossau, Mathieu De Craene, André Goossen, David Prater, Jose Rivero

Patent number: 12102482Abstract: The invention provides for a method for switching between fields of view of an ultrasound probe. The method begins by obtaining an anatomical model representing a region of interest of a subject and establishing a first field of view relative to an ultrasonic probe, wherein the first field of view comprises an initial portion of the region of interest. Ultrasound data is then obtained from the first field of view by way of the ultrasonic probe and a first anatomical feature is identified within the first field of view based on the ultrasound data. A location in digital space of the first field of view relative to the anatomical model is determined based on the first anatomical feature. A second field of view is then established based on the anatomical model and the first field of view, wherein the first field of view functions as a reference field of view. The field of view is then switched from the first field of view to the second field of view.Type: GrantFiled: March 13, 2020Date of Patent: October 1, 2024Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Frank Michael Weber, Irina Waechter-Stehle, Tobias Wissel, Arne Ewald, Matthias Lenga, Jochen Peters

Publication number: 20240127432Abstract: A system and method for achieving more accurate results when applying an image processing task to a series of medical images of a patient, without significantly increasing processing resource. The proposed system and method is based on receiving a plurality of image sequences of a particular anatomical region, each capturing cyclical movement of an anatomical object. Each image sequence is supplied to a classifier module which employs use of one or more machine learning algorithms to derive at least one score for each image sequence indicative of predicted success or quality of a result of the image processing task if applied to the given image series. This permits an assessment to be made in advance of which of the plurality of image series is most likely to result in the best (e.g. highest quality, or greatest amount of information) results from the image processing task.Type: ApplicationFiled: January 24, 2022Publication date: April 18, 2024Inventors: Alexandra Groth, Tanja Lossau, Irina Waechter-Stehle, Frank Michael Weber, Jochen Peters, Sebastian Wild, Arne Ewald, Andre Goossen

Publication number: 20240090849Abstract: The present invention relates to multispectral imaging. In order to improve an identification of relevant multispectral material transitions (in particular caused by injected contrast agent), an apparatus is proposed to use the local maxima of the variances and/or covariances of the intensities of the multi-channel images to locate material transitions. In comparison to gradient vectors, the local variance is not directed and not prone to noise. An alternative apparatus is proposed to use the local covariance deficits of the intensities of the multi-channel images to locate material transitions. The proposed alternative approach is independent of spatial drifts across the image volume.Type: ApplicationFiled: November 28, 2021Publication date: March 21, 2024Inventors: RAFAEL WIEMKER, LIRAN GOSHEN, HANNES NICKISCH, CLAAS BONTUS, TOM BROSCH, JOCHEN PETERS, ROLF JÜRGEN WEESE
