Method and computer system for automatically generating a statistical model

摘要

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.

1. A method for automatically generating a statistical vascular model of a patient group, the method comprising:
collecting tomographical image data records of vascular structures of the patient group; 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 vascular landmark coordinates, the centerline coordinates and the vessel contour coordinates, using the body landmarks, to patient-related registered vascular coordinates models; determining patient-related vascular parameter models from the vascular landmark coordinates, neighborhood relationships of the vascular landmarks, characteristic geometrical parameters describing the vessel centerlines, and a shape of a vessel contour as a function of a relative distance from a given one of the vascular landmarks; merging the patient-related vascular parameter models to form at least one statistical vascular parameter model, determining statistical parameters of the at least one statistical vascular parameter model; and at least one of saving and outputting the at least one statistical vascular parameter model.
