摘要：
A computer-implemented method for pre-processing image data of a three-dimensional volume includes providing the image data of a vessel, applying a super-sampling filter to the image data to generate super-sampled image data having an increased resolution as compared to the image data, applying an unsharp masking filter to the super-sampled image data for increasing contrast of an edge of the vessel, applying a de-noising filer for removing noise surrounding the edge after applying the unsharp masking filter, and storing the image data after applying the de-noising filter thereto.
