Patent number: 11298096Abstract: The invention provides a method of patient monitoring following endovascular aneurysm repair (EVAR) with a stent graft. It particularly applies to abdominal aortic aneurysm repair. A first 3D volume scan of the stent in situ is provided and a second, subsequent 3D volume scan of the stent is also provided. One or more fiducial markers are generated in a first image derived from the first scan and in a second image derived from the second scan. The fiducial markers identify recognizable features of the stent, such as the bifurcation point in the stent graft. A rigid 3D transform mapping based on the one or more fiducial markers is extracted and then a registration is applied to the first and second scans based on the 3D rigid transform between the first and second images. A size value is derived at the same location in the aneurysm from the first and second scans. The same location is determined with reference to the registered first and second images of the stent.Type: GrantFiled: July 12, 2018Date of Patent: April 12, 2022Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Laurence Rouet, Antoine Collet-Billon, Cecile Dufour, Robert Randall Entrekin

Patent number: 10410409Abstract: An ultrasound system and method are described for acquiring standard views of the fetal heart simultaneously with real-time imaging. A matrix array probe is manipulated until a first standard view such as a 4-chamber view is acquired. The first standard view image is matched to its corresponding plane in a fetal heart model. From the matched plane of the heart model, the orientations of the other standard views are known from the geometrical relationships of structures within the heart model. This orientation information is used to control the matrix array probe to automatically scan the planes of all of the standard views simultaneously in real-time.Type: GrantFiled: July 26, 2017Date of Patent: September 10, 2019Assignee: Koninklijke Philips N.V.Inventors: James Robertson Jago, Alasdair Dow, Antoine Collet Billon, Lisa Kay Pumphrey

Patent number: 10290076Abstract: A system and method for image registration includes tracking (508) a scanner probe in a position along a skin surface of a patient. Image planes corresponding to the position are acquired (510). A three-dimensional volume of a region of interest is reconstructed (512) from the image planes. A search of an image volume is initialized (514) to determine candidate images to register the image volume with the three-dimensional volume by employing pose information of the scanner probe during image plane acquisition, and physical constraints of a pose of the scanner probe. The image volume is registered (522) with the three-dimensional volume.Type: GrantFiled: March 2, 2012Date of Patent: May 14, 2019Assignees: The United States of America, as represented by the Secretary, Department of Health and Human Services, Koninklijke Philips N.V.Inventors: Samuel Kadoury, Jochen Kruecker, James Robertson Jago, Bradford Johns Wood, Antoine Collet-Billon, Cecile Dufour

Patent number: 9357978Abstract: An ultrasonic diagnostic imaging system acquires 3D data sets of the fetal heart by use of a gating signal synthesized from detected motion of the fetal heart. A sequence of temporally different echo signals are acquired from a location in the anatomy where motion representative of the heart cycle is to be estimated, such as a sample volume in the fetal carotid artery or an M line through the fetal myocardium. A heart cycle signal is synthesized from the detected motion and used to gate the acquisition of fetal heart image data at one or more desired phases of the fetal heart cycle. In an illustrated embodiment 3D data sets are acquired from multiple subvolumes, each over the full fetal heart cycle, then combined to produce a live 3D loop of the beating fetal heart.Type: GrantFiled: June 2, 2010Date of Patent: June 7, 2016Assignee: Koninklijke Philips N.V.Inventors: Alasdair Dow, Antoine Collet-Billon, James Jago, Lisa Kay Pumphrey, Paul R.

Publication number: 20110201935Abstract: In an ultrasound imaging system (UIS), an ultrasound scanning assembly (USC) provides volume data (VD) resulting from a three-dimensional scan of a body (BDY). A feature extractor (FEX) searches for a best match between the volume data (VD) and a geometrical model (GM) of an anatomical entity. The geometrical model (GM) comprises respective segments representing respective anatomic features. Accordingly, the feature extractor (FEX) provides an anatomy-related description (ARD) of the volume data (VD), which identifies respective geometrical locations of respective anatomic features in the volume data (VD). In a preferred embodiment, a slice generator (SLG) generates slices (SX) from the volume data (VD) based on the anatomy-related description (ARD) of the volume data (VD).Type: ApplicationFiled: October 15, 2009Publication date: August 18, 2011Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Antoine Collet-Billon, James Jago, Alasdair Dow, Lisa Pumphrey

Patent number: 7526113Abstract: An image processing method for processing a sequence of images of a distortable 3-D Object, each image being registered at a corresponding image instant within the interval of time of the sequence having steps to construct and display an image of said 3-D Object represented with regions, each region showing a quantified indication relating to its maximal contraction or relaxation within said interval of time. Each region of the constructed and displayed image is attributed a respective color of a color coded scale that is function of the calculated quantified indication relating to the maximum of contraction or relaxation of said region. The quantified indications may be the instant when a face or region has had its maximum of contraction or relaxation; or the phase value corresponding to said maximum; or the delay to attain said maximum.Type: GrantFiled: May 21, 2002Date of Patent: April 28, 2009Assignee: Koninklijke Philips Electronics N.V.Inventors: Marie Jacob, Olivier Gerard, Antoine Collet-Billon
