Perspectives of Computer Assisted Medical Imaging
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 axe overlaid, the low contrast for soft tissue requires highly trained and experienced radiologists to read those images. With the advent of modern computers, imaging techniques could be developed, that deliver cross-sectional images, such as Computer Tomography (CT) and Magnetic Resonance Imaging (MRI) as shown in fig. 1. They do not have the problem of overlays, but they still show only a limited two-dimensional aspect of the anatomy, which is three-dimensional in nature.
