    摘要: A method and a system for determining a physical property of an object, e.g., a diameter value of an anatomical structure, employs local object context information for determining a local physical property of the object. The context information may be a known or determined cross-sectional shape of the object. In one embodiment, a processor may be configured to provide volumetric image information of the object having a three-dimensional structure; determine the physical property of the object along its three-dimensional structure; determine the object context information of the object; and visualize the object context information and the physical property on a display.

    摘要: The invention relates to evaluating medical image information, in particular physical properties of an object (32). When preparing a surgical procedure e.g. a minimally invasive procedure, it may be beneficial to plan the procedure in detail before starting the operation. Thus, obtaining precise information about physical properties of an object (32), e.g. a diameter value (34, 36) of an anatomical structure may be beneficial. Accordingly, a method and a system for determining a physical property (34, 36) of an object (32) is provided, which employs local object context information (38) for determining a local physical property of the object (32).

    摘要: A system for establishing a contour of a structure is disclosed. An initialization subsystem (1) is used for initializing an adaptive mesh representing an approximate contour of the structure, the structure being represented at least partly by a first image, and the structure being represented at least partly by a second image. A deforming subsystem (2) is used for deforming the adaptive mesh, based on feature information of the first image and feature information of the second image. The deforming subsystem comprises a force-establishing subsystem (3) for establishing a force acting on at least part of the adaptive mesh, in dependence on the feature information of the first image and the feature information of the second image. A transform-establishing subsystem (4) is used for establishing a coordinate transform reflecting a registration mismatch between the first image, the second image, and the adaptive mesh.

    摘要: The invention relates to an image registration apparatus for registering a first image and a second image with respect to each other. A model, which has a fixed topology, is adapted to the first image for generating a first adapted model and to the second image for generating a second adapted model, and corresponding image elements (40, 48, 49; 50, 58, 9) are determined in the first image and in the second image based on spatial positions of first image elements in the first image with respect to the first adapted model and spatial positions of second image elements in the second image with respect to the second adapted model. Since the model has a fixed topology, corresponding image elements can relatively reliably be found based on the adapted models, even if the first and second images show objects having complex properties like a heart, thereby improving the registration quality.
