  • Publication number: 20210077062
    Abstract: The invention provides a method for making anatomical measurements using a captured ultrasound image representative of the anatomical region of interest. The method comprises receiving (20) data representative of a set of points selected by a user within the image and interpreting from the points a particular anatomical measurement type which the user is intending to perform. In particular, the points are processed to identify (24) a pattern or other geometrical characteristic of the points, and the location (22) of at least one of the points within the image is also identified. These two characteristics are used to identify from the set of points which measurement the operator is performing. Once the measurement is identified, an appropriate measurement template (26) is selected and applied in order to derive (30) from the set of points an anatomical measurement.

  • Patent number: 10902606
    Abstract: A system (100) for segmenting a coronary artery vessel tree (182) of a patient heart in a three dimensional (3D) cardiac image (120) includes a coronary volume definition unit (150) and a coronary artery segmentation unit (180). The coronary volume definition unit (150) sets a spatial boundary (210, 220) from internal and external surfaces of heart tissues in the 3D cardiac image based on a fitted heart model (200). The coronary artery segmentation unit (180) segments the coronary artery vessel tree (182) in the 3D cardiac image using a segmentation algorithm with a search space limited by the spatial boundary set from the internal and external surfaces of the heart tissues.

  • Publication number: 20200129153
    Abstract: The present invention relates the device and the method for providing a guidance signal. The device preferably relates to a mobile device, such as a mobile tablet computer. The device comprises an input unit, a display and a processing unit. Via the input unit, a three-dimensional outline image of a surface of a human subject is provided, e.g. acquired by a camera. The device further comprises a memory. The memory stores a human reference model, which statistically represents a virtual human subject. In practice it is often the case that the surface outline represented by the human reference model would not instantly fit to the surface outline of the human subject. Therefore, the processing unit is configured to adapt the human reference model resulting in an adapted model, such that the surface outline represented by the adapted model fits to the surface outline of the (real) human subject.

  • Publication number: 20200022609
    Abstract: The invention provides for a medical imaging system (700) comprising: a memory (734) for storing machine executable instructions (740), a display (732) for rendering a user interface (800), and a processor (730). Execution of the machine executable instructions causes the processor to receive (1000) three dimensional medical image data (746) descriptive of a region of interest (709) of a subject (718). The region of interest comprises a spine (200). Execution of the machine executable instructions further causes the processor to receive (1002) a set of spinal coordinate systems (748) each descriptive of a location and an orientation of spinal vertebrae in the three dimensional medical image data. The set of spinal coordinate systems further comprises a set of spine centerline positions (102) each positioned on a spine centerline (108).

  • Patent number: 10102347
    Abstract: The invention relates to a system for producing a representation of an object in image data, based on a template coupled to a model of the object, the system comprising a model unit for adapting the model to the object in the image data, and a template unit for adapting the template to the adapted model on the basis of the coupling between the template and the model. The template defines a representation of the object which is simpler to interpret than the model. Because the template of the invention is coupled to the model, the position, orientation and/or shape of the template is determined by the model adapted to the object in the image data. Hence, the template is adapted to the image data. The adapted template is capable of representing the object and its individual characteristics.

  • Patent number: 9867586
    Abstract: A double focal spot X-ray tube is used to acquire a set of two images PI?, PI? for a given gantry position from slightly different view positions. The stereo or binocular disparity (BD) of imaged structures is used to estimate the object depth in view direction, which in turn is used to discriminate between objects inside IO and outside EO the body. Respective structures are virtually removed from the images PI?, PI?.
