1. A system for segmentation of a blood vessel of a subject in a medical image wherein the medical image comprises a plurality of slices, the system comprising a processor for executing the steps of:
automatically identifying a plurality of landmark slices in the plurality of slices, the plurality of landmark slices containing each anatomical landmark of one or more anatomical landmarks in the medical image;
automatically identifying relevant landmark slices for finding the blood vessel based on positional relationships of the landmarks and the blood vessel;
automatically prompting for manual identification of a seed for the blood vessel in response to being unable to automatically identify a blood vessel component;
receiving an input indicative of manual identification of the seed for the blood vessel from within a set of slices that is constrained to the relevant landmark slices; and
automatically segmenting the blood vessel based on the input indicative of manual identification of the seed for the blood vessel from within a set of slices that is constrained to the relevant landmark slices.
