A method and a computer system are disclosed for automatically generating a statistical vascular model of a patient group. In at least one embodiment, the method includes collecting determining patient-related vascular coordinates models from a multiplicity of vascular landmark coordinates of vascular landmarks, centerline coordinates on vessel centerlines and vessel contour coordinates on vessel contour edge profiles; determining body landmark coordinates of body landmarks; registering the vessel-related coordinates to patient-related registered vascular coordinates models; merging patient-related vascular parameter models to form at least one statistical vascular parameter model; determining the statistical parameters thereof; and saving and/or outputting the at least one statistical vascular parameter model.
