Patent number: 12062185Abstract: A method and system for mapping boundary detecting features of at least one source triangulated mesh of known topology to a target triangulated mesh of arbitrary topology. A region of interest in a volumetric image associated with each triangle of the target triangulated mesh is provided to a feature mapping network. The feature mapping network assigns a feature selection vector to each triangle of the target triangulated mesh. The associated region of interest and assigned feature selection vector for each triangle of the target triangulated mesh are provided to a boundary detection network. A predicted boundary based on features of the associated region of interest selected by the assigned feature selection vector is obtained from the boundary detection network.Type: GrantFiled: February 5, 2021Date of Patent: August 13, 2024Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Christian Buerger, Tobias Klinder, Alexander Schmidt-Richberg

Patent number: 11935245Abstract: The invention provides for a medical apparatus (100, 400, 600) comprising a memory (110) for storing machine executable instructions (120) and a processor (104) for controlling the medical apparatus. Execution of the machine executable instructions causes the processor to: receive (200) a medical image (122) descriptive of a three-dimensional anatomy of a subject (418); and provide (202) an image segmentation (124) by segmenting the medical image into multiple tissue regions (300, 302) using a model-based segmentation. The model-based segmentation assigns a tissue type to each of the multiple regions. The model-based segmentation has a surface mesh (304). The segmentation is corrected by using the tissue type assigned to each of the multiple regions to correct for partial volume effects at boundaries formed by the surface mesh between at least some of the multiple tissue regions.Type: GrantFiled: September 27, 2019Date of Patent: March 19, 2024Assignee: Koninklijke Philips N.V.Inventors: Steffen Renisch, Christian Buerger

Publication number: 20240005484Abstract: A system and related method for image processing. The system comprises an input (IN) interface for receiving two segmentation maps for an input image. The two segmentation maps (11,12) obtained by respective segmentors, a first segmentor (SEG1) and a second segmentor (SEG2). The first segmentor (SEG1) implements a shape-prior-based segmentation algorithm. The second segmentor (SEG2) implements a segmentation algorithm that is not based on a shape-prior, or at least the second segmentor (SEG2) accounts for one or more shape priors at a lower weight as compared to the first segmentor (SEG1). A differentiator (DIF) configured to ascertain a difference between the two segmentation maps. The system may allow detection of abnormalities.Type: ApplicationFiled: October 9, 2021Publication date: January 4, 2024Inventors: CHRISTIAN BUERGER, JENS VON BERG, MATTHIAS LENGA, CRISTIAN LORENZ

Patent number: 11684801Abstract: For delivering an image-guided radiation therapy treatment to a moving structure included in a region of a patient body a series of first images of the region of the patient body in different phases of a motion of the structure is acquired in accordance with a first imaging mode. The series of first images is associated with a series of second images of the patient body in essentially the same phases of the motion of the target structure, the second images being acquired in a second imaging mode. During the treatment, a third image is acquired using the second imaging mode during the radiation therapy treatment and a continuation of the radiation therapy treatment is planned on the basis of data relating to one of the first images selected on the basis of a comparison between the third image and the second images associated with the first images.Type: GrantFiled: March 19, 2018Date of Patent: June 27, 2023Assignee: Koninklijke Philips N.V.Inventors: Nicole Schadewaldt, Tim Nielsen, Christian Buerger

Publication number: 20230038965Abstract: Presented are concepts for initialising a model for model-based segmentation of an image which use specific landmarks (e.g. detected using other techniques) to initialize the segmentation mesh. Using such an approach, embodiments need not be limited to predefined model transformations, but can initialise a segmentation mesh with arbitrary shape. In this way, embodiments may provide for an image segmentation algorithm that not only delivers a robust surface-based segmentation result but also does so for strongly varying target structure variations (in terms of shape).Type: ApplicationFiled: February 11, 2021Publication date: February 9, 2023Inventors: CHRISTIAN BUERGER, TOBIAS KLINDER, JENS VON BERG, ASTRID RUTH FRANZ, MATTHIAS LENGA, CRISTIAN LORENZ

Ultrasonic diagnosis of cardiac performance using heart model chamber segmentation with user control
Patent number: 11510651Abstract: An ultrasonic diagnostic imaging system has a user control by which a user positions the user's selection of a heart chamber border in relation to two myocardial boundaries identified by a deformable heart model. The user's border is positioned by a single degree of freedom control which positions the border as a function of a single user-determined value. This overcomes the vagaries of machine-drawn borders and their mixed acceptance by clinicians, who can now create repeatably-drawn borders and exchange the control value for use by others to obtain the same results.Type: GrantFiled: June 18, 2020Date of Patent: November 29, 2022Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Irina Waechter-Stehle, Frank Michael Weber, Christian Buerger, Robert Joseph Schneider, David Prater, Scott Holland Settlemier, Michael Daniel Cardinale -
Patent number: 11389245Abstract: There is provided a computer-implemented method (200) and apparatus for determining a transformation for anatomically aligning fragments of a broken bone. An image of the broken bone of the subject is acquired (202). The bone is broken into two or more fragments. A model of a corresponding unbroken bone and at least one parameter is acquired. The at least one parameter defines one or more deformations to the model that are permitted when fitting portions of the model of the unbroken bone to corresponding fragments of the broken bone (204). Portions of the model of the unbroken bone are fit to corresponding fragments of the broken bone based on the at least one parameter (206). A transformation is determined that anatomically aligns the fragments of the broken bone with the corresponding portions of the model (208).Type: GrantFiled: June 26, 2018Date of Patent: July 19, 2022Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Joerg Sabczynski, Christian Buerger, Michael Grass
