Anatomie realism comes to diagnostic imaging K. H. Höhne, M. Domans, B. Pflesser, A. Pommert, M. Riemer, Th. Schiemann, U. Tiede Institute of Mathematics and Computer Science in Medicine University of Hamburg, Martinistraße 52, D-20246 Hamburg 1. Introduction For over decades after the discovery of the X-rays by Wilhelm Konrad Röntgen medical imaging techniques did not change: X-rays were cast through the patient and the shadows caused by the anatomical structures were recorded on photographic film. Beside the fact that the shadows of different objects are overlaid, the low contrast for soft tissue requires highly trained and experienced radiologists to interprete these images. With the advent of modern Computers, imaging techniques could be developed that deliver cross-sectional images, such äs Computer Tomography and Magnetic Resonance Imaging äs shown in figure 1. They do not have the problem of overlays, but they still show only a limited twodimensional aspect of the anatomy which is really three-dimensional in nature. In principle there is no reason to image the human body just this way, it is more or less a consequence of the technical development. If we were asked nowadays to design an imaging System without the knowledge about X-ray projection
