    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.

    摘要: A method, computer program and device for creating a viewing protocol for medical images is described. At least a first site of interest is identified in a medical imaging data set captured from the patient. Patient record data or computer assisted detection information can be used to identify the site of interest, which may be a potential lesion. A viewing protocol for displaying medical images to a user is planned. The viewing protocol includes a viewing path along which an image of the site of interest will be displayed. The viewing protocol also includes a trigger associated with the site of interest. When the trigger event is encountered the dynamic mode of image display is reconfigured to dynamically highlight the site of interest. The viewing protocol can then be used to control the display of images so as to provide, for example, a virtual endoscope.
