Abstract
A method for processing image data representing a three-dimensional volume, the data comprising image values for a three-dimensional grid of voxels, comprising: starting from a given voxel building up a vector path along a first dimension of the three dimensional volume, connecting a number of voxels of two-dimensional slices of the grid adjacent in the first dimension, the connected voxels representing a spatial neighborhood of the given voxel, including structurally related voxels of the three-dimensional grid; averaging the image values of the voxels of the vector path to obtain a first averaged value, assigned to the given voxel position; repeating the aforementioned steps for a number of voxels; repeating the aforementioned steps on the first averaged values, employing vector paths along a second dimension being different from the first dimension, obtaining second averaged values; and on the second averaged values repeating the aforementioned steps, employing vector paths along a third dimension being different from the first and the second dimension. Thus, filtered values are obtained that constitute processed image data representing the three dimensional volume.
