A method for filtering of tomography 3d - illustrations according to the reconstruction of volume data

摘要

A method for filtering of tomography 3d - representations of an object to be examined, wherein for the representation of the object to be examined a solid model is used, which the volume of the object to be examined in a plurality of three-dimensional image voxels having individual image values, and divides the image value of each voxel an object-specific property of the object to be examined in this volume, where the following method steps are performed:– according to the reconstruction of the total volume for each image voxel of the variances, be in a predetermined range or radius r is calculated so as to the spatial orientation of a contrast jump to determine by the tangential plane t, whereby this plane, by means of the vectors v_min. and v_⟘ is clamped, wherein, in turn, the vector v_⟘ normal to the vectors v_min. and v_{a maximum} a plane, and the vector v_{a maximum} in the direction with the largest amount of the variance and the vector v_min. in the direction with the smallest amount of the variance shows,– the image values within the tangential plane t with a two-dimensional folding be filtered,..
