Patent number: 11877893Abstract: A method and processing system for providing a three-dimensional, 3D, ultrasound image along with an additional ultrasound acquisition. A location of the additional ultrasound acquisition with respect to the three-dimensional ultrasound image is determined or obtained. After obtaining the 3D ultrasound image and the additional ultrasound acquisition, initial display data is for display of only the 3D ultrasound image. In response to a user input, second display data is generated for displaying both the 3D ultrasound image and the additional ultrasound acquisition. The display of the additional ultrasound acquisition is based on the location of the additional ultrasound acquisition with respect to the three-dimensional ultrasound image.Type: GrantFiled: February 25, 2019Date of Patent: January 23, 2024Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Laurence Rouet, Cecile Dufour, Robert Randall Entrekin, Gary Cheng-How Ng

Patent number: 11464489Abstract: An ultrasonic diagnostic imaging system produces an image of shear wave velocities by transmitting push pulses to generate shear waves. A plurality of tracking lines are transmitted and echoes received by a focusing beamformer adjacent to the location of the push pulses. The tracking lines are sampled in a time-interleaved manner. The echo data acquired along each tracking line is processed to determine the time of peak tissue displacement caused by the shear waves at points along the tracking line, and the times of peaks at adjacent tracking lines compared to compute a local shear wave velocity. The resultant map of shear wave velocity values is color-coded and displayed over an anatomical image of the region of interest.Type: GrantFiled: June 28, 2019Date of Patent: October 11, 2022Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Roy Beck Peterson, Yan Shi, Hua Xie, Jean-Luc Francois-Marie Robert, Vijay Thakur Shamdasani, Robert Randall Entrekin, Anna Teresa Fernandez

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: 9251593Abstract: The invention concerns a medical imaging system comprising means (4) of segmenting a region of interest around an object of interest within a volume of 3D data (3DV). The system according to the invention comprises means (5) of calculating a sub-regions map (CSR) within the segmented region (RS) and correction means (6) intended to exclude sub-regions of the segmented region by means of said sub-regions map (CSR). The correction can be made automatically or manually by means of control means (7) enabling a user to select the sub-regions to be excluded. Display means (3) make it possible to display a 2D representation (2DR) of the volume of 3D data (3DV) and the segmented region (RS, RS?) at various stages of the processing.Type: GrantFiled: March 18, 2004Date of Patent: February 2, 2016Assignee: Koninklijke Philips N.V.Inventors: Nicolas Villain, Claude Cohen-Bacrie, Jean-Michel LaGrange, Claire Levrier, Robert Randall Entrekin

Patent number: 8852107Abstract: An ultrasonic diagnostic imaging system produces an extended field of view (EFOV) image. A 3D imaging probe is moved along the skin of a patient above the anatomy which is to be included in the EFOV image. As the probe is moved, images are acquired from a plurality of differently oriented image planes such as a sagittal plane and a transverse plane. As the probe is moved the image data of successive planes of one of the orientations is compared to estimate the motion of the probe. These motion estimates are used to position a succession of images acquired in one of the orientations accurately with respect to each other in an EFOV display format. The motion estimates are also used to display a graphic on the display screen which indicates the progress of the scan to the user as the probe is being moved. The progress may be indicated in terms of probe velocity, distance traveled, or the path traversed by the moving probe.Type: GrantFiled: June 2, 2009Date of Patent: October 7, 2014Assignee: Koninklijke Philips N.V.Inventors: Yangmo Yoo, James Jago, Jing-Ming Jong, Robert Randall Entrekin, Martin Anderson, Lars Jonas Olsson

Publication number: 20110105900Abstract: The present invention relates to a transducer unit for an ultrasonic breast imaging system, in which an acoustic coupler is employed which comprises a frame in which a transducer is mounted. The frame is open at one end, and a surface of the transducer is exposed at the open end. The frame and exposed transducer surface are put under compression against the surface of a compression plate with a gasket, or similar, providing a fluid-tight seal therebetween. A thin layer of acoustic couplant is provided between the transducer surface and the compression plate. The frame defines a chamber around the nonexposed surface of the transducer, the chamber housing an acoustic couplant.Type: ApplicationFiled: June 9, 2005Publication date: May 5, 2011Applicant: Koninklijke Philips Electronics N.V.Inventor: Robert Randall Entrekin

Publication number: 20090268952Abstract: A method for determining the presence or absence of malignant features in medical images, wherein a plurality of base comparison or training images of various types of lesions taken of actual patient is examined by one or more image reading experts to create a first database array. Low-level features of each of the lesions in the same plurality of base comparisons or training images arc determined using one or more image processing algorithms to obtain a second database array set. The first and second database array set are combined to create a training database array set which is input to a learning system that discovers/learns a classifier that maps from a subset of the low-level features to the expert's evaluation in the first database array set. The classifier is used to determine the presence of a particular mid-level feature in an image of lesion in a patient based solely on the image.Type: ApplicationFiled: December 13, 2005Publication date: October 29, 2009Applicant: Koninklijke Philips Electronics, N.V.Inventors: James David Schaffer, Walid Ali, Larry Eshelman, Claude Cohen-Bacrie, Jean-Michel Lagrange, Claire Levrier, Nicolas Francois Villain, Robert Randall Entrekin

Publication number: 20080255452Abstract: A method for performing enhanced ultrasound diagnostic breast imaging includes using first and second compression plates (62,64) configured for receiving and compressing a breast between the same. The breast extends from a chest wall (118) of a patient at a proximate end to a nipple at a distal end. Portions of the breast proximate the nipple and proximate lateral edges of the breast are in non-contact with the second compression plate during breast compression. An ultrasound transducer array (68) moves along a path to scan the breast, the ultrasound transducer array being disposed adjacent a side of the second plate (64) opposite the breast. Image data representative of the breast is acquired as the ultrasound transducer array (68) traverses the path.Type: ApplicationFiled: September 22, 2005Publication date: October 16, 2008Applicant: KONINKLIJKE PHILIPS ELECTRONICS, N.V.Inventor: Robert Randall Entrekin
