In many cases x-ray images are the only basis for surgery
planning. Nevertheless it is desirable to draw conclusions
about the 3D-anatomy of the patient from such data. This
work presents a method to reconstruct 3D shapes from few
digital x-ray images on the basis of 3D-statistical shape
models. At the core of this method lies an algorithm which
optimizes a similarity measure assessing the difference be-
tween projections of the shape model and the x-ray images.
Based on theoretical and experimental observations we pro-
pose to measure the distance between the silhouettes of the
object in the projections. The method is tested on 23 syn-
thetically generated x-rays from CT data sets of the the geo-
metrically as well as topologically complex shape of the
