Abstract: A method for determining an apposition parameter indicative for the position and apposition of a tubular member, such as a stent graft, inserted in a lumen of an anatomical vessel/duct of a patient. The method includes providing a numerical three-dimensional patient model of at least a part of the vessel including the tubular member; determining a vessel morphology parameter from the patient model, the parameter indicative for the anatomy of a predetermined part of the vessel at or near the tubular member in said vessel with respect to said patient model; determining a tubular member positional parameter from the patient model, the parameter indicative for the position of a predetermined part of the tubular member in the patient model; and calculating, based on the determined vessel morphology parameter and tubular member positional parameter, the relative position of the tubular member with respect to the vessel as the apposition parameter.
