A method for automatically segmenting three-dimensional blood vessel data from three-dimensional medical image data of a patient through the use of a computer is provided. The method includes: receiving the three-dimensional medical image data of the patient; generating three-dimensional shape machine-learning blood vessel data from the received three-dimensional medical image data through the use of a machine-learned segmentation program so as to generate three-dimensional blood vessel data; and generating corrected three-dimensional shape blood vessel data from the received three-dimensional medical image data and the generated three-dimensional shape machine-learning blood vessel data through the use of an image processing program.
