A model-based approach to the reconstruction of three dimensional arteries from biplane angiograms

This paper describes the automatic production of three dimensional computer models of arteries, where the originating data is a pair of biplane X-ray angiograms. By developing the process of reconstruction using a hierarchy of generic models, it is possible to build a limited number of plausible reconstructions. There are indications that further research will be able to identify the unique reconslmclion that matches the original structure. The process avoids the extensive human operator intervention and simplifying assumptions used by other researchers.
