Shape reconstruction using X-ray images

摘要

The invention concerns a method for generating a three-dimensional model of a structure based on at least one two-dimensional image of the structure comprising the steps of:
a) obtaining a general three-dimensional model of the structure;
b) obtaining the at least one two-dimensional image of the structure;
c) determining at least an image feature from the image obtained in step b);
d) determining the orientation of the general three-dimensional model of the structure relative to the at least one two-dimensional image of the structure so that the image feature(s) of a two-dimensional projection of the three-dimensional model match or is closely related to the two-dimensional image feature(s) obtained in step c)
characterised in that
e) the three-dimensional model is morphed after the orientation of the three-dimensional model has been determined in step d) to fit the form or shape of the three-dimensional model to the at least one two-dimensional image.
