Abstract: A computer-implemented method for visualization of an elongated anatomical structure (20), for example of a fetal spine using ultrasound is provided. The method comprising the steps of: receiving a plurality of 3D ultrasound image volumes, each image volume depicting at least a portion of an elongated anatomical structure (20); on each 3D ultrasound image volume, automatically or semi-automatically fitting a parametric curve (30) to the depicted portion of the elongated anatomical structure, the parametric curve being defined by curve parameters; reformatting each 3D ultrasound image volume by applying a transformation which straightens the parametric curve along at least one axis, so as to generate a plurality of reformatted image volumes and reformatted parametric curves (32, 34); registering the reformatted image volumes with one another by determining the joining point of their respective parametric curves; and fusing the reformatted image volumes with one another to yield a fused image depicting the whole elongated anatomical structure or a larger portion thereof than the 3D ultrasound image volumes.

Abstract: An ultrasound image processing apparatus (200) is disclosed for obtaining a biometric measurement of an anatomical feature of interest from a 3D ultrasound image. The apparatus comprises a display apparatus (50) communicatively coupled to a processor arrangement (210) adapted to render a volumetric ultrasound image (300) from the 3-D ultrasound image and control the display apparatus to display said rendered image; receive a plurality of user inputs (303) highlighting the anatomical feature of interest, each input corresponding to a pixel of the displayed volumetric ultrasound image; estimate a depth of each of said pixels in the volumetric ultrasound image (300); define a 3-D path (307) in the volumetric ultrasound image based on the received user inputs along said estimated depths; perform a processing operation based on the defined 3-D path; and control the display apparatus to display the processing operation result, wherein the processing operation based on the defined 3-D path comprises at least one of a measurement of a length of the 3-D path (307); a reorientation of the rendered volumetric ultrasound image (300); and a generation of a 2-D image slice (400) of the 3-D ultrasound image based on the defined 3-D path. Also disclosed are an ultrasound imaging system including such an ultrasound image processing apparatus, a computer-implemented method and a computer program product for implementing this method on a computer.

Abstract: Methods and systems are provided for displaying a 3D ultrasound image volume in a desired view orientation. A 3D ultrasound image can be acquired of an anatomical feature in a patient. The actual orientation of the anatomical feature can be determined in space. The 3D ultrasound image including the anatomical feature can be displayed such that the anatomical feature is positioned in a selected orientation that is different than the actual orientation, and in relation to a lighting model for generating lighting and shadowing on the anatomical feature.

Abstract: A medical imaging system configured to analyze an acquired image to determine the imaging plane and orientation of the image. The medical imaging system may be further configured to determine a location of an aperture to acquire a key anatomical view and transmit instructions to a controller to move the aperture to the location. A sonographer may not need to move the ultrasound probe for the medical imaging system to move the aperture to the location. An ultrasound probe may include a transducer array that may have one or more degrees of freedom of movement within the probe. The transducer array may be translated by one or more motors that receive instructions from the controller to position the aperture.

Abstract: The invention provides for a method of obtaining a composite 3D ultrasound image of a region of interest. The method includes obtaining preliminary ultrasound data from a region of interest of a subject and identifying an anatomical feature within the region of interest based on the preliminary ultrasound data. A first imaging position and one or more additional imaging positions are then determined based on the anatomical feature. A first 3D ultrasound image is obtained from the first imaging position and one or more additional 3D ultrasound images are obtained from the one or more additional imaging positions, wherein a portion of the first 3D ultrasound image overlaps a portion of the one or more additional 3D ultrasound images, thereby forming an overlapping portion comprising the anatomical feature. Spatial registration is performed between the first 3D ultrasound image and the one or more additional 3D ultrasound images based on the anatomical feature the 3D ultrasound images are then blended based on the spatial registration, thereby generating a composite 3D ultrasound image.

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: A mechanism for automatically generating and ranking M-mode lines for generating or defining M-mode data usable to assess fetal heart activity, e.g. determine a fetal heart rate. A region of interest, containing a fetal heart, in a sequence of ultrasound images is identified. The region of interest is used to define the position of each of a plurality of M-mode lines, e.g. anatomical M-mode lines. A quality measure of each M-mode line is determined based on M-mode data generated for each M-mode line, and the quality measures are then used to rank the M-mode lines.
