We report on the results of a collaboration between two independent research projects. In one, we have been developing a software system for the detection and display of surfaces of organs and organ systems from three-dimensional reconstructions; in the other, we have been developing hardware and software for the three-dimensional reconstruction of objects using nuclear magnetic resonance zeugmatographic imaging. The merging of these two modalities gives us a truly powerful tool for three-dimensional visualization. This is demonstrated by frames from movies illustrating the external and internal three-dimensional structure of organs, such as the brain and the heart, produced by applying the display programs to the nuclear magnetic resonance reconstructions.
