    摘要： A method of removing undesirable objects such as bones from a digital medical image is disclosed. In the preferred embodiment, the method comprises the steps of generating a symbolic representation of the medical image, wherein said symbolic representation comprises a directed graph comprising vertices and edges, wherein each pixel or voxel of the digital medical image is associated with an edge of the graph, and wherein the root of said directed graph is not located within said undesirable object; electing, by user input, a site located within said undesirable object; determining a path in the symbolic representation, said path including the edge associated with said elected site and propagating towards the root of said directed graph; visualizing the part of the image associated with said determined path; identifying within said visualized part of the image the transition between the undesired object and the remainder of the image; and removing the part of the image associated with the branch of the graph rooted at said transition between the undesired object and the remainder of the image.

    摘要： An embodiment is directed to a method and a system for assisting the targeting of a target with an elongate instrument, wherein the instrument is to be inserted into a living object's body part along a predetermined trajectory extending between an entry point of said instrument into said body part and a target point associated with said target. The method comprises an instrument directing assisting step for generating and displaying an image allowing a user to assess to which extend the longitudinal axis of the instrument is aligned with the vector connecting the target point and the tip portion of said instrument. Also, the method comprises an instrument guiding assisting step of generating and displaying an image allowing a user to assess to which extent the instrument motion during insertion thereof coincides with the predetermined trajectory.

    摘要： The invention relates to a method for navigation during medical interventions on tubular organ structures, characterized in that, before the intervention, static image data of the tubular organ structures are recorded and stored, the tubular organ structures are extracted from the image data and their course is converted into a geometric description used during the medical intervention for instrument/organ recording, and the instrument that is spatially localized by a tracking system is successively corrected in relation to the static data, by a transformation that is preferably defined by an optimization method, taking into account the geometric description and information on the previous distance covered by the instrument, or, conversely, the static data are successively corrected in relation to the instrument position, and thus the position of the instrument is associated with the anatomical structures in the static image data.
