Publication number: 20230021018Abstract: The invention provides a method for performing an assessment of a placenta. The method includes obtaining a 3D ultrasound image of a uterus (210) and segmenting the placenta (220). A 3D rendering (200) of the uterus is then generated, wherein the generating includes: identifying a position of the placenta within the uterus with respect to an anatomical structure such as the cervix (250); obtaining anatomical reference data relating to a potential risk associated with the position of the placenta within the uterus; and comparing the position of the placenta and the anatomical reference data. A 3D rendering of the uterus is generated that comprises a 3D rendering of the placenta, marked with an indicator that is altered based on the comparison of the position of the placenta and the anatomical reference data. The appearance of the indicator may vary according to e.g. risk type/severity.Type: ApplicationFiled: December 8, 2020Publication date: January 19, 2023Inventors: Cybele Ciofolo-Veit, Laurence Rouet, Caroline Denise Francoise Raynaud, Thierry Lefevre

Patent number: 11341634Abstract: A computer implemented method is provided for processing a 3D fetal ultrasound image. A 3D fetal ultrasound image is obtained (either acquired or received from memory), and the spine is detected within the image. This enables a first reference axis to be defined. A second reference axis is defined perpendicular to the first reference axis, and the 3D fetal ultrasound image is updated (e.g. rotated in 3D space) using the first and second reference axes and an up/down (elevation) orientation detection. This provides a normalization of the orientation of the image, so that a machine learning approach is better able to identify landmarks within new images.Type: GrantFiled: July 12, 2018Date of Patent: May 24, 2022Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Caroline Denise Francoise Raynaud, Laurence Rouet, Cybèle Ciofolo-Veit, Thierry Lefevre, David Nigel Roundhill

Publication number: 20210345987Abstract: The invention provides an ultrasound imaging method for determining complementary views of interest based on an anomalous feature identified in a region of interest of an ultrasound image. The method includes obtaining an ultrasound image of a region of interest of a subject and identifying an anomalous feature within said region. The identified anomalous feature may then be used to determine one or more available complementary ultrasound images of interest of the subject. The one or more available complementary ultrasound images may then be displayed to a user and the complementary ultrasound views to be reviewed may then be selected by the user from the displayed available complementary ultrasound images.Type: ApplicationFiled: September 29, 2019Publication date: November 11, 2021Inventors: Cybèle Ciofolo-Veit, Thierry Lefevre, Caroline Denise Francoise Raynaud, Laurence Rouet

Publication number: 20210338203Abstract: The invention provides a method for guiding the acquisition of an ultrasound image. A 3D ultrasound image is acquired by an ultrasound probe at a first position and an anatomical structure is identified within the 3D ultrasound image. A target imaging plane is estimated based on the identified anatomical structure and it is determined whether the target imaging plane is present within the 3D ultrasound image. If the target imaging plane is present, a displacement between a central plane of the 3D ultrasound image and the target plane is determined. If the displacement is below a predetermined threshold, the target imaging plane is extracted and if the displacement is above the predetermined threshold, an instruction to acquire a 3D ultrasound image with the ultrasound probe at a second position, different from the first position, is generated based on the displacement. The invention further provides a method for estimating a target imaging plane.Type: ApplicationFiled: October 14, 2019Publication date: November 4, 2021Inventors: Laurence ROUET, Cybèle CIOFOLO-VEIT, Thierry LEFEVRE, Caroline Denise Francoise RAYNAUD, Cristian LORENZ, Tobias KLINDER, Nicole SCHADEWALDT, Alexander SCHMIDT-RICHBERG
