  • Patent number: 10402970
    Abstract: A system and method is provided for performing a model-based segmentation of a medical image which only partially shows an anatomical structure. In accordance therewith, a model is applied to the image data of the medical image, the model-based segmentation providing an adapted model having a first model part having been adapted to the first part of the anatomical structure in the medical image of the patient, and a second model part representing the second part of the anatomical structure not having been adapted to a corresponding part of the medical image. Metadata is generated which identifies the first model part to enable the first model part to be distinguished from the second model part in a further processing of the adapted model. Advantageously, the metadata can be used to generate an output image which visually indicates to the user which part of the model has been personalized and which part of the model has not been personalized.

  • Patent number: 10282846
    Abstract: A method is provided for generating a deformable model (300) for segmenting an anatomical structure in a medical image. The anatomical structure comprises a wall. The deformable model (300) is generated such that it comprises, in addition to two surface meshes (320, 360), an intermediate layer mesh (340) for being applied in-between a first surface layer of the wall and a second surface layer of the wall. In generating the intermediate layer mesh (340), the mesh topology of at least part (400) of the intermediate layer mesh is matched to the mesh topology of one of the surface meshes (320, 360), thereby establishing matching mesh topologies. The deformable model (300), as generated, better matches the composition of such walls, thereby providing a more accurate segmentation.

  • Publication number: 20190096118
    Abstract: The invention provides a ‘model-based’ imaging system in which surface values to be applied to a segmented surface of an imaged body are determined on the basis of projections cast into the volume of the imaged body, the projections made at angles and depths determined on the basis of information encoded within an anatomical model. In examples, the angles and depths are determined on the basis of a comprehensive segmentation of the imaged body, itself performed on the basis of the anatomical model. By locally varying projection angles and depths around the body, in dependence upon local anatomical context, improved imaging of the internal structure of the imaged body may be achieved. In particular, images may be generated providing representations of the internal structure which are of greater clinical utility or relevance. 4D data sets may also be better handled, through use of anatomical context to maintain consistency in representations across multiple frames.

  • Publication number: 20180161009
    Abstract: An ultrasonic diagnostic imaging system has a user control by which a user positions the user's selection of a heart chamber border in relation to two myocardial boundaries identified by a deformable heart model. The user's border is positioned by a single degree of freedom control which positions the border as a function of a single user- determined value. This overcomes the vagaries of machine-drawn borders and their mixed acceptance by clinicians, who can now create repeatably-drawn borders and exchange the control value for use by others to obtain the same results.

  • Patent number: 9659370
    Abstract: The present invention relates to a method for segmenting MR Dixon image data. A processor and a computer program product are also disclosed for use in connection with the method. The invention finds application in the MR imaging field in general and more specifically may be used in the generation of an attenuation map to correct for attenuation by cortical bone during the reconstruction of PET images. In the method, a surface mesh is adapted to a region of interest by: for each mesh element in the surface mesh: selecting a water target position based on a water image feature response in the MR Dixon water image; selecting a fat target position based on a fat image feature response in the MR Dixon fat image; and displacing each mesh element from its current position to a new position based on both its water target position and its corresponding fat target position.

  • Publication number: 20160270683
    Abstract: The invention relates to a system for determining electrical characteristics like electrical potentials on a surface of a heart (5). An esophageal electrode structure (6) measures electrical characteristics within an esophagus and a position determination unit (34) determines the position of the esophageal electrode structure within the esophagus and the position of the surface of the heart (5). The electrical characteristics on the surface of the heart (5) are then determined based on the measured electrical characteristics and based on the determined positions of the esophageal electrode structure (6) and the surface of the heart (5). Since for measuring the electrical characteristics the esophageal electrode structure (6) is used, the electrical characteristics can be measured within the esophagus and thus close to the surface of the heart (5), thereby allowing for an improved accuracy of determining the electrical characteristics on the surface of the heart (5).
