Abstract

A method for determining a three-dimensional form of a body from two-dimensional projection images includes producing at least one projection image of the body and producing corresponding model projection images from a generic model of the body. The body projection images and the model can be input into a computer-assisted processing unit and the generic model can be adjusted to the body by comparing image contents of the body projection images with the model projections images at a two-dimensional level only. The three-dimensional form of the body can be determined from the adjusted generic model.
