Abstract :
This work is concerned with the three-dimensional (3-d) shape and pose reconstruction of the human rib cage from few
two-dimensional (2-d) radiographs. The reconstruction method is based on a statistical shape model of the rib cage that
is adapted to the 2-d image data of a patient. An underlying optimization process minimizes a distance measure which
quantifies the dissimilarities between 2-d projections of the 3-d shape model and the X-ray images and thereby esti-
