    摘要: The present invention is related to a method and system for acquiring information on lesions in dynamic 3D medical images of a body region and/or organ. The method comprises the steps of :
    - applying a registration technique to align a plurality of volumetric image data of the body region and/or organ, yielding multi-phase registered volumetric image data of the body region and/or organ,
    - applying a hierarchical segmentation on the multi-phase registered volumetric image data of the body region and/or organ, said segmentation yielding a plurality of clusters of n-dimensional voxel vectors of the muiti-phase aligned volumetric image,
    - determining from the plurality of clusters a cluster or set of clusters delineating the body and/or organ,
    - identifying the connected region(s) of voxel vectors belonging to the body region and/or organ,
    - refine/fill the connected region(s) corresponding to the body region and/or organ
    - reapplying the segmentation step to the refined/filled connected region(s) corresponding to the body region and/or organ, to obtain a more accurate segmentation,
    - acquiring information on the presence of lesions in a cluster or set of clusters of said plurality of clusters.

    摘要: The present invention relates to a method for processing and presenting at least a first image and a second image, these images being digital medical images. A first step in the method is performing image registration between the first image and the second image to generate a pixel-level mapping between both images a second step is presenting the first image and the second image simultaneously on a display. A third step is presenting a first magnification of a region in the first image and a second magnification of a corresponding region in the second image. The corresponding region in the second image being determined based on the pixel-level registration mapping.

    摘要: Method of constructing a gray value model and/or a geometric model of an anatomic entity in a 3D digital medical image.
    A gray value model is generated encoding photometric knowledge at landmark positions. This step exploits intensity correlation in neighborhoods sampled around landmark positions.
    A geometric model is generated encoding geometric knowledge between landmarks. This step exploits spatial correlation between landmarks of segmented anatomic entities.
    The topology of the landmarks on the surface or volume of the anatomic entity is encoded in a graph structure.
