Patent number: 10368763Abstract: An apparatus, a method and a computer program for visualizing a conduction tract of a heart include adapting a generic heart model to match geometrical data of a patient's heart, where model data, corresponding to the generic heart model and indicating a shape and/or position of the conduction tract, is modified in accordance to the adaptation of the generic heart model. The modification of the model data is further refined based on electrophysiological data of the patient to produce refined model data, and the refined model data is used for generating a visualization of a refined model heart indicating a refined shape and/or refined position of the conduction tract of the patients heart.Type: GrantFiled: March 1, 2013Date of Patent: August 6, 2019Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Alexandra Groth, Juergen Weese, Helko Lehmann, Hans Barschdorf

Patent number: 9953040Abstract: A system for accessing a database of a plurality of image data sets includes an acquisition unit which acquires a query for searching the database for an image data set or an image data subset comprised in an image data set. The query includes at least one medically relevant term which defines a search criteria. A determining unit determines the image data set or the image data subset included in the image data set based on the strength of semantic matches between the at least one medically relevant term and (a) corresponding medical annotation(s) describing the image data set. A retrieving unit retrieves the determined image data set or image data subset from the database.Type: GrantFiled: July 25, 2008Date of Patent: April 24, 2018Assignee: Koninklijke Philips N.V.Inventors: Juergen Weese, Helko Lehmann, Yuechen Qian, Warner Rudolph Theophile Ten Kate

Patent number: 9754411Abstract: The invention relates to a system (100) for visualizing an object of interest comprised in a volume of an image dataset, the system comprising a path unit (110) for specifying a path in the volume of the image dataset on the basis of the object of interest, a location unit (120) for determining a location on a projection ray through the volume of the image dataset on the basis of the specified path, and a value unit (130) for computing a projected gray value corresponding to the projection rayon the basis of the determined location on the projection ray. Because the locations on the projection ray are determined based on the specified path for indicating the object of interest, the actual computation of the projection gray values may be designed and constructed to show gray values describing the object of interest while hiding gray values describing other objects, in particular occluding objects.Type: GrantFiled: September 11, 2008Date of Patent: September 5, 2017Assignee: Koninklijke Philips N.V.Inventors: Dieter Geller, Helko Lehmann

Patent number: 8995777Abstract: The invention relates to an image registration apparatus for registering a first image and a second image with respect to each other. A model, which has a fixed topology, is adapted to the first image for generating a first adapted model and to the second image for generating a second adapted model, and corresponding image elements (40, 48, 49; 50, 58, 9) are determined in the first image and in the second image based on spatial positions of first image elements in the first image with respect to the first adapted model and spatial positions of second image elements in the second image with respect to the second adapted model. Since the model has a fixed topology, corresponding image elements can relatively reliably be found based on the adapted models, even if the first and second images show objects having complex properties like a heart, thereby improving the registration quality.Type: GrantFiled: November 24, 2011Date of Patent: March 31, 2015Assignee: Koninklijke Philips N.V.Inventors: Jochen Peters, Juergen Weese, Helko Lehmann

Publication number: 20120035963Abstract: When generating radiology reports, image findings and/or clinical information is automatically mapped to an appropriate standardized structured report template. The report template contains placeholders for information such as case-specific images and measureable values, and the placeholders are filled in by either the radiologist or by automatic procedures such as image processing algorithms, text extraction algorithms, or the like. In this manner, the radiologist is assisted in effectively generating a reader-independent high-quality diagnostic report.Type: ApplicationFiled: February 11, 2010Publication date: February 9, 2012Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Yuechen Qian, Helko Lehmann, Juergen Weese, Merlijn Sevenster, Eric Zachary Silfen, Sabri Boughorbel

Patent number: 7889900Abstract: A method, computer program and device for creating a viewing protocol for medical images is described. At least a first site of interest is identified in a medical imaging data set captured from the patient. Patient record data or computer assisted detection information can be used to identify the site of interest, which may be a potential lesion. A viewing protocol for displaying medical images to a user is planned. The viewing protocol includes a viewing path along which an image of the site of interest will be displayed. The viewing protocol also includes a trigger associated with the site of interest. When the trigger event is encountered the dynamic mode of image display is reconfigured to dynamically highlight the site of interest. The viewing protocol can then be used to control the display of images so as to provide, for example, a virtual endoscope.Type: GrantFiled: February 7, 2006Date of Patent: February 15, 2011Assignee: Koninklijke Philips Electronics N.V.Inventors: Juergen Weese, Eric Thelen, Gundolf Kiefer, Helko Lehmann, Ali Majidi, Jochen Peters
