    摘要: A system and method for registering pre-operative images of an object with an intra-operative image of the object is disclosed. Prior to an operative procedure, Digitally Reconstructed Radiographs (DRRs) are generated for the pre-operative images of each individual patient. Signatures are extracted from the DRRs. The signatures are stored in a knowledge base. During the operative procedure, a signature is extracted from the intra-operative image. The intra-operative signature is compared to the stored pre-operative signatures. A pre-operative image having a best signature match to the intra-operative signature is retrieved. The retrieved pre-operative image is registered with the intra-operative image.

    摘要: The invention relates to a method and a device for generating a virtual installation model (2) as an image of a real installation (1). As a database therefor, digital picture data (4) representing pictures of a real installation (1) on the one hand and installation components (13) of a component library (6) on the other hand are used. The data of the installation components as well as the digital picture data (4) of the real installation (1) is evaluated by means of an image analysis (5). Based on this analysis, the identified installation components (13) are assigned to the virtually generated installation model (2). The virtual image of the real installation thus created serves to document the actual structure of the installation/facility, to simplify failure analysis, e.g., in areas that are difficult to access, and/or to operate and monitor the installation/facility. In addition to geometric data, functional data, etc. of the installation components are also stored.

    摘要: A method is disclosed for combining a first image and a second image of an examination object, which images have an overlap region. A corresponding magnetic resonance scanner is also disclosed. In at least one embodiment, a superposed image is determined in the overlap region as a weighted superposition of the first image and the second image with a spatially variable weighting function. The first image and the second image are transformed on the basis of a comparison of the first image and/or the second image with the superposed image.
