摘要： A method includes obtaining image data generated by an imaging system (100), generating data indicative of a degree to which each of a plurality of voxels of the image data corresponds to one or more predetermined geometrical features, wherein each geometrical feature is assigned a different color, generating a signal indicative of a single color value for each of the plurality of voxels based on the degree and the colors, generating a volumetric rending of the image data based on the signal, generating a link between voxels of the volumetric rendering and voxels of the image data, and visually presenting the image data and the volumetric rendering concurrently. The geometrical features represent local shape features which are determined by ray casting with the rays being used for the computation of a quadric represented by a matrix and with the eigenvalues of said matrix determine the degree to which voxels correspond to some local geometric shape features (i.e. blobness, tubularness).
