A method for manufacturing a three-dimensional anatomical structure comprising the steps of obtaining a plurality of medical images containing at least one anatomical region of interest, wherein each anatomical region of interest is defined based on a grey level value on the medical images; segmenting each medical image based on the anatomical region of interest to obtain the grey level value; converting the grey level values of the respective segmented medical images into vector data; interpolating the vector data of each segmented medical image to form a three-dimensional data; and producing a three-dimensional anatomical structure of the region of interest from the three-dimensional data.
