The visualization of human anatomy for diagnostic, therapeutic, and
educational pur poses has long been a challenge for scientists and
artists. In vivo medical imaging could not be introduced until the
discovery of X-rays by Wilhelm Conrad ROntgen in 1895. With the
early medical imaging techniques which are still in use today, the
three-dimensional reality of the human body can only be visualized
in two-dimensional projections or cross-sections. Recently,
biomedical engineering and computer science have begun to offer the
potential of producing natural three-dimensional views of the human
anatomy of living subjects. For a broad application of such
technology, many scientific and engineering problems still have to
be solved. In order to stimulate progress, the NATO Advanced
Research Workshop in Travemiinde, West Germany, from June 25 to 29
was organized. It brought together approximately 50 experts in
3D-medical imaging from allover the world. Among the list of topics
image acquisition was addressed first, since its quality decisively
influences the quality of the 3D-images. For 3D-image generation -
in distinction to 2D imaging - a decision has to be made as to
which objects contained in the data set are to be visualized.
Therefore special emphasis was laid on methods of object
definition. For the final visualization of the segmented objects a
large variety of visualization algorithms have been proposed in the
past. The meeting assessed these techniques.
