    Abstract: The present invention relates to a device, system and method for segmentation of images. The device comprises an input (20) configured to obtain image data including a first image slice of a plurality of image slices of a 3D image data set, first segmentation of the first image slice in which at least one object is segmented, and a second image slice of the plurality of image slices of the 3D image data set. A processing unit (21, 21a) is configured to compute a second segmentation of the second image slice based on the obtained image data by applying a trained algorithm or computing system that has been trained on a plurality of segmentations of a plurality of objects in a plurality of image slices onto the obtained image data to propagate the segmentation of the at least one object in the first segmentation from the first image slice to the second image slice and to compute a third segmentation of a third image slice arranged, within the 3D image data set, in between the first and second image slices. An output (22) is configured to output the second segmentation of the second image slice and the third segmentation of the third image slice.

    Abstract: An ultrasound imaging apparatus (10) for segmenting an anatomical object in a field of view (29) of an ultrasound acquisition unit (14) is disclosed. The ultrasound imaging apparatus comprises a data interface (32) configured to receive a two-dimensional ultrasound data (30) of the object in the field of view in an image plane from the ultrasound acquisition unit and to receive a three-dimensional segmentation model (46) as a three-dimensional representation of the object from a segmentation unit (36). An image processor (34) is configured to determine a two-dimensional segmentation model (50) on the basis of the three-dimensional segmentation model and a segmentation plane (48), wherein the segmentation plane and an image plane of the two-dimensional ultrasound data correspond to each other. The image processor is configured to adapt a contour of the two-dimensional segmentation model to the two-dimensional ultrasound data on the basis of pattern detection and where the image processor is configured to provide annotated two-dimensional image data (42) on the basis of the two-dimensional ultrasound data and the adapted segmentation model aligned to the two-dimensional ultrasound data.

    Abstract: The invention relates to a medical image data processing system (101) for image segmentation. The medical image data processing system (101) comprises a machine learning framework trained to receive an anatomical position of a voxel and to provide a tissue type classification. An execution of machine executable instructions by a processor (130) of the medical image data processing system (101) causes the processor (130) to control the medical image data processing system (101) to: —receive medical image data (140) comprising an anatomical structure of interest, —fit an anatomical frame of reference (302, 402) to the medical image data (140) using model-based segmentation, —classify tissue types represented by voxels of the medical image data (140) using the machine learning framework, wherein anatomical positions of the voxels with respect to the anatomical frame of reference (302, 402) are used as the input to the machine learning framework.

    Abstract: An ultrasound imaging apparatus is disclosed comprising an ultrasound acquisition unit (10) connected to a plurality of ultrasound probes (42, 44, 46, 70, 72, 74) each for providing ultrasound data suitable for ultrasound imaging of a patient (12) in a field of view (32) of the ultrasound probes. The ultrasound imaging apparatus further comprises a detection unit (20) for detecting an anatomical object (36) of the patient in the field of view on the basis of the ultrasound data received from at least one of the ultrasound probes and for determining a spatial relationship of the anatomical object and each of the ultrasound probes. A selection unit (24) coupled to the detection unit selects at least one of the ultrasound probes on the basis of an acquisition quality of at least one physical parameter detectable from the ultrasound data, wherein the acquisition quality is determined on the basis of the spatial relationship (38) of the anatomical object and each of the ultrasound probes and at least one anatomical feature of the anatomical object. An evaluation unit coupled to the ultrasound acquisition unit receives the ultrasound data from the at least one selected ultrasound probe and determines the at least one physical parameter on the basis of the ultrasound data received from the selected ultrasound probe.

    Abstract: An apparatus includes an imaging probe and is configured for dynamically arranging presentation of visual feedback (144) for guiding manual adjustment, via the probe, of a location, and orientation, associated with the probe. The arranging is selectively based on comparisons (321) between fields of view of the probe and respective results of segmenting image data acquired via the probe. In an embodiment, the feedback does not include (175) a grayscale depiction of the image data. Coordinate system trans formations corresponding to respective comparisons may be computed. The selecting may be based upon and dynamically responsive to content of imaging being dynamically acquired via the probe.
