Patent number: 11790753Abstract: A method for monitoring the loneliness state of a subject includes receiving proximity information for a plurality of user devices and then generating a loneliness decision for subjects who use the devices based on the proximity information. In one case, the proximity information may be projected onto a lower dimensional space, distance values corresponding to the proximity information may be compared, and the user devices may be ranked based on the comparison. A user may then be determined to be lonely based on the ranking of the user devices. In other cases, clustering techniques may be applied relative to one or more centroids. Distances may then be calculated and compared for purposes of generating a loneliness decision. In other cases, resource information may be taken into consideration with distance information for generating a loneliness decision.Type: GrantFiled: April 1, 2021Date of Patent: October 17, 2023Assignee: Koninklijke Philips N.V.Inventors: Giulio Valenti, Salvatore Saporito, Sabine Mollus

Patent number: 10719980Abstract: A method of analyzing a tube system in particular by image processing of images of the tube system is provided by the present invention. In order to achieve a simulation of a medium flow through a calculated tube model, the present invention gathers a tube model from a specific tube data set. By defining the necessary parameters of a virtual injection of the medium by the user, the medium flows through the model. Using this displayed simulation for generating at least two images leads to an artificial image sequence that might support a person, which wants to examine a real structure, that corresponds to the calculated model. This might be seen in.Type: GrantFiled: March 2, 2009Date of Patent: July 21, 2020Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Sabine Mollus, Joerg Bredno, Juergen Weese, Drazenko Babic

Patent number: 10426430Abstract: An ultrasound system for planning a surgical implantation of a prosthetic aortic valve produces three dimensional images of the aortic root region of a patient. An electronic model of an aortic root is accessed and fitted to the aortic root in a three dimensional ultrasound image. Preferably the aortic root model exhibits closed contour cross-sections which are fitted to the endothelial lining of the aortic root in the ultrasound image. A medial axis of the fitted model is identified and radii measured from the medical axis to the border of the fitted model. The radii are joined to identify a surface forming a mesh model fitted to the aortic root anatomy of the patient. The shape and dimensions of the fitted model may be used to fabricate a custom prosthetic valve for aortic valve replacement.Type: GrantFiled: August 24, 2011Date of Patent: October 1, 2019Assignee: Koninklijke Philips N.V.Inventors: Lyubomir Georgiev Zagorchev, Michael Cardinale, Scott Holland Settlemier, Kevin CamHong Quan, Sabine Mollus, Juergen Weese, Ivan Salgo

Patent number: 9684972Abstract: An imaging apparatus for imaging an object includes a geometric relation determination unit configured to determine a geometric relation between first and second images of the object. A marker determination unit configured to determine corresponding marker locations in the first and second images and marker appearances based on the geometric relation such that the marker appearances of a first marker to be located at a first location in the first image and of a second marker to be located at a second corresponding location in the second image are indicative of the geometric relation. The images with the markers at the respective corresponding locations are shown on a display unit. Since the marker appearances are indicative of the geometric relation between the images, a comparative reviewing of the images can be facilitated, in particular, if they correspond to different viewing geometries.Type: GrantFiled: January 25, 2013Date of Patent: June 20, 2017Assignee: Koninklijke Philips N.V.Inventors: Juergen Weese, Irina Wächter-Stehle, Thomas Heiko Stehle, Alex Saalbach, Sabine Mollus, Nicole Schadewaldt, Lyubomir Georgiev Zagorchev

Patent number: 9393079Abstract: A method and an image processing system for the evaluation of projection images generated by an X-ray imaging system, wherein the images may show different instruments of a given set of interventional instruments like catheters or guide wires. The instruments are equipped with markers such that their configuration is characteristic of the corresponding instrument. Preferably three markers are arranged on a straight line, the ratio of the distances between them being characteristic for the corresponding instrument. The image processing system may then identify the instruments present in a given projection and provide functionalities for a user that correspond to said instruments. Moreover, the system may be used to locate an instrument of interest in a projection image if the marker configuration of that instrument is known a priori.Type: GrantFiled: July 21, 2005Date of Patent: July 19, 2016Assignee: Koninklijke Philips N.V.Inventors: Juergen Weese, Sabine Mollus, Raoul Florent, Lucile Nosjean, Pierre Lelong, Peter Maria Johannes Rongen
