  • Publication number: 20150104090
    Abstract: A method and a system are disclosed for interactively creating and/or modifying a hollow organ representation on the basis of medical-technical image data of a hollow organ. An embodiment of the method includes providing the medical-technical image data together with a hollow organ course line representing the course of the hollow organ; providing a plurality of contour representations of a contour of the hollow organ representation along the hollow organ course line; receiving a command input for the input and/or modification of a selected contour representation and/or of the hollow organ course line; locally modifying (H) the contour of the hollow organ representation on the basis of the command input, taking into consideration a number of contour representations adjacent to the selected contour representation on at least one side along the hollow organ course line, using an automatic interpolating sweep algorithm.

  • Publication number: 20130223748
    Abstract: A method is disclosed for determining a boundary surface network of a tubular object. An ordered series of contours is first supplied on the basis of image data in a source space. A transformation function is created for at least two consecutive contours in the series, and a unit space segment object is created in the unit space on the basis of the consecutive contours. A local signed distance function is determined in the unit space. In addition, a relative positional information of a query point is determined in the source space from a surface of a segment object in the source space, the segment object being based on the consecutive contours, on the basis of the local signed distance function in the unit space and using the transformation function. Finally, the boundary surface network is created on the basis of the relative positional information that has been determined.
