A method for imaging a blood vessel (2) comprises the steps of: providing a two-dimensional view of the vessel; calculating a region of interest (40); defining a characterizing base path (13) of the vessel; within the region of interest (40), calculating a base line (22) perpendicular to the base path (13); along the base line (22), determining a transition where the base line intersects a side edge (2a, 2b) of the vessel; finding such transitions for many base lines; considering the collection of transitions as defining a side edge (27, 28) of the vessel; allowing a user to input an amendment command, and in response to receiving a user input amendment command, amending at least a portion of the region of interest and repeating the calculation with the amended region of interest. |
