1. A medical imaging system for segmenting an original blood vessel of a body part represented by an original medical image, comprising: an image analyzer adapted to receive and analyze the original medical image for providing a Hessian Eigen analysis comprising a first data and a second data mapped to each pixel of the original medical image; and an image identifier adapted to receive the Hessian Eigen analysis for identifying seed points from the pixel by processing the first data and the second data along with a vesselness property, wherein the seed points are used for segmenting the original blood vessel to provide a corrected medical image representing a corrected blood vessel.
