Patent number: 10332238Abstract: Image processing method or apparatus (IP) to transform a 3D image data set (DS) into a visually protected one (DSX). The 3D image set includes an object region (OR) and a background region (BR) that defines s silhouette of an imaged object (P). An inadvertent or malicious direct volume rendering of the silhouette (IF) of the object is prevented by applying a randomization operation to at least the background region (BR).Type: GrantFiled: June 22, 2015Date of Patent: June 25, 2019Assignee: Koninklijke Philips N.V.Inventors: Rafael Wiemker, Thomas Buelow, Tobias Klinder, Martin Bergtholdt, Irina Waechter-Stehle

Patent number: 10331981Abstract: A system and method are provided for brain tissue classification, which involves applying an automated tissue classification technique to an image of a brain based on a prior probability map, thereby obtaining a tissue classification map of the brain. A user is enabled to, using a user interaction subsystem, provide user feedback which is indicative of a) an area of misclassification in the tissue classification map and b) a correction of the misclassification. The prior probability map is then adjusted based on the user feedback to obtain an adjusted prior probability map, and the automated tissue classification technique is re-applied to the image based on the adjusted prior probability map. An advantage over a direct correction of the tissue classification map may be that the user does not need to indicate the area of misclassification or the correction of the misclassification with a highest degree of accuracy. Rather, it may suffice to provide an approximate indication thereof.Type: GrantFiled: April 25, 2016Date of Patent: June 25, 2019Assignee: Koninklijke Philips N.V.Inventors: Fabian Wenzel, Thomas Heiko Stehle, Lyubomir Georgiev Zagorchev, Jochen Peters, Martin Bergtholdt, Carsten Meyer

Patent number: 10282917Abstract: A system and method are provided for interactive editing of a mesh which has been applied to a three-dimensional (3D) image to segment an anatomical structure shown therein. To facilitate the interactive editing of the applied mesh, a view of the 3D image is generated which shows a mesh part to be edited, with the view being established based on a local orientation of the mesh part. Advantageously, the view may be generated to be substantially orthogonally to the mesh part, or to a centerline of the anatomical structure which is determined as a function of the mesh part. Accordingly, an orthogonal view is established which facilitates the user in carrying out the editing action with respect to the mesh part. It is therefore not needed for the user to manually navigate through the 3D image to obtain a view which is suitable for mesh editing, which is typically time consuming.Type: GrantFiled: June 29, 2016Date of Patent: May 7, 2019Assignee: Koninklijke Philips N.V.Inventors: Thomas Heiko Stehle, Fabian Wenzel, Carsten Meyer, Lyubomir Georgiev Zagorchev, Martin Bergtholdt, Jochen Peters

Patent number: 9833213Abstract: A method, system and program product are provided for planning an intervention procedure in a body lumen. A CT scan of the body lumen is performed. A virtual rendering is created of the inside of the body lumen corresponding to an interventional camera image. Then a virtual tape corresponding to a planned path for the intervention procedure is projected onto a wall of the body lumen. The virtual tape is projected onto the lumen wall, which is relatively distant from the camera point on the virtual rendering, so the tape does not appear to oscillate like a central thread. Also, since the virtual tape is located on the lumen wall, it does not occlude the center of the lumen, allowing a user to better visualize the lumen during planning, during fly through, and even during an actual intervention.Type: GrantFiled: January 12, 2012Date of Patent: December 5, 2017Assignee: Koninklijke Philips N.V.Inventors: Rafael Wiemker, Tobias Klinder, Martin Bergtholdt

Patent number: 9684961Abstract: The invention relates to a scan region determining apparatus (12) for determining a scan region of a subject to be scanned by a scanning system (10) like a computed tomography system. A spatial transformation defining a registration of an overview image and a template image with respect to each other is determined, wherein initially the overview image and the template image are registered by using an element position indicator being indicative of a position of an element of the subject with respect to the overview image. A template scan region is defined with respect to the template image, wherein a final scan region is determined by projecting the template scan region onto the overview image by using the determined spatial transformation. The registration and thus the determination of the spatial transformation are very robust, which improves the quality of determining the final scan region.Type: GrantFiled: February 26, 2014Date of Patent: June 20, 2017Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Julien Senegas, Axel Saalbach, Martin Bergtholdt, Thomas Netsch, Peter Mazurkewitz
