Abstract: 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. A central plane of a 3D ultrasound image is obtained, wherein the central plane contains at least part of an anatomical structure and abounding box is generated around the anatomical structure. The bounding box is divided into a grid having a plurality of grid points and, for each grid point; an offset is estimated between the central plane and the target imaging plane. Finally, coordinates of the target imaging plane are estimated based on the offset for each grid point of the bounding box.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: The invention relates to a device (1) for positioning a marker (2) in a 3D ultrasonic image volume (3), a system for positioning a marker (2) in a 3D ultrasonic image volume (3), a method for positioning a marker (2) in a 3D ultrasonic image volume (3), a computer program element for controlling such device (1) for performing such method and a computer readable medium having stored such computer program element. The device (1) comprises an image provision unit (11), a marker unit (12) and a display unit (13). The image provision unit (11) is configured to provide a 3D ultrasonic image volume (3) showing an object (4). The marker unit (12) is configured to position a marker (2) in the 3D ultrasonic image volume (3). The display unit (13) is configured to display the 3D ultrasonic image volume (3) and the marker (2) in a first imaging view (31) in a first imaging plane and in a second imaging view (32) in a second, different imaging plane. The positioning of the marker (2) is limited to be on a projection line (5). The first and the second imaging views are rotated relative to each other, so that the projection line (5) has a first angle relative to the first imaging plane and a second, different angle relative to the second imaging plane.
