Vascular selection from images

A method of segmenting a vascular image into vascular paths for defining paths of blood flow, the method comprising:

• receiving, in a processor, the vascular image;
• defining, via the processor, first and second targeted vascular path end regions within the vascular image;
• segmenting, via the processor, the vascular image to identify the positions of vascular portions in the vascular image;
• automatically generating, via the processor, a plurality of vascular path options from the identified vascular portions, each vascular path option defining a potential vascular path that extends between the first and second targeted vascular path end regions;
• displaying, via the processor, the plurality of vascular path options registered to the vascular image for selection by a user, each of the displayed vascular path options including the first and second targeted vascular path end regions;
• receiving, in the processor, a path option selected by the user for defining a path of blood flow;
• and
• adjusting, removing, or adding vascular path options for other targeted vascular path end regions that are within the vascular image based on the path option selected by the user.
